Answer:

[tex]\dfrac{\ln | \sec (x-b)- \ln | \sec (x-a)}{\sin (a-b)}+\text{C}[/tex]

Step-by-step explanation:

Fundamental Theorem of Calculus

[tex]\displaystyle \int \text{f}(x)\:\text{d}x=\text{F}(x)+\text{C} \iff \text{f}(x)=\dfrac{\text{d}}{\text{d}x}(\text{F}(x))[/tex]

If differentiating takes you from one function to another, then integrating the second function will take you back to the first with a constant of integration.

Given indefinite integral:

[tex]\displaystyle \int \sec(x-a) \sec (x-b)\:\text{d}x[/tex]

[tex]\boxed{\begin{minipage}{3.5 cm}\underline{Trigonometric Identity}\\\\$\sec \theta=\dfrac{1}{\cos \theta}$\\\end{minipage}}[/tex]

Therefore:

[tex]\implies \displaystyle \int \dfrac{1}{\cos(x-a)} \cdot \dfrac{1}{\cos (x-b)}\:\text{d}x[/tex]

[tex]\implies \displaystyle \int \dfrac{1}{\cos(x-a)\cos (x-b)} \:\text{d}x[/tex]

[tex]\textsf{Multiply the integral by }\dfrac{\sin (a-b)}{\sin (a-b)}:[/tex]

[tex]\implies \displaystyle \int \dfrac{1}{\cos(x-a)\cos (x-b)} \cdot \dfrac{\sin (a-b)}{\sin (a-b)}\:\text{d}x[/tex]

Take the constant outside the integral:

[tex]\implies \displaystyle \dfrac{1}{\sin (a-b)}\int \dfrac{\sin (a-b)}{\cos(x-a)\cos (x-b)} \:\text{d}x[/tex]

Rewrite the numerator:

[tex]\implies \displaystyle \dfrac{1}{\sin (a-b)}\int \dfrac{\sin [(x-b)-(x-a)]}{\cos(x-a)\cos (x-b)} \:\text{d}x[/tex]

[tex]\boxed{\begin{minipage}{6 cm}\underline{Trigonometric Identity}\\\\$\sin (A \pm B)=\sin A \cos B \pm \cos A \sin B$\\\end{minipage}}[/tex]

Therefore:

[tex]\implies \displaystyle \dfrac{1}{\sin (a-b)}\int \dfrac{\sin(x-b) \cos (x-a)-\cos (x-b) \sin (x-a)}{\cos(x-a)\cos (x-b)} \:\text{d}x[/tex]

[tex]\implies \displaystyle \dfrac{1}{\sin (a-b)}\int \dfrac{\sin(x-b) \cos (x-a)}{\cos(x-a)\cos (x-b)} -\dfrac{\cos (x-b) \sin (x-a)}{{\cos(x-a)\cos (x-b)}}\:\text{d}x[/tex]

[tex]\implies \displaystyle \dfrac{1}{\sin (a-b)}\int \dfrac{\sin(x-b)}{\cos (x-b)} -\dfrac{\sin (x-a)}{\cos(x-a)}\:\text{d}x[/tex]

[tex]\boxed{\begin{minipage}{3.5 cm}\underline{Trigonometric Identity}\\\\$\tan \theta=\dfrac{\sin \theta}{\cos \theta}$\\\end{minipage}}[/tex]

Therefore:

[tex]\implies \displaystyle \dfrac{1}{\sin (a-b)}\int \tan(x-b)-\tan(x-a)\:\text{d}x[/tex]

[tex]\boxed{\begin{minipage}{4.3 cm}\underline{Integrating $\tan x$}\\\\$\displaystyle \int \tan x\:\text{d}x=\ln | \sec x|+\text{C}$\end{minipage}}[/tex]

Therefore:

[tex]\implies \dfrac{1}{\sin (a-b)}\left[ \ln | \sec (x-b)- \ln | \sec (x-a)\right]+\text{C}[/tex]

[tex]\implies \dfrac{\ln | \sec (x-b)- \ln | \sec (x-a)}{\sin (a-b)}+\text{C}[/tex]

Math reality is more restrictive and logical, physical reality is more "free" and well-behaved.

Mathematics are a logical construct, thus, everything in the "mathematical realty" must follow a certain logic.

For example, in math, always that you do a simplification (like rounding, applying a theorem, using an integration property, etc) you need to prove logically why you can do that.

While on physics we assume the reality is "nice" and we can always apply the simplifications. This is because most of the functions that represent physics are nice (continuous, differentiable, etc)  functions, in the same way, most of the matrices are square matrices, and so on.

Concluding, for example in math the number 4.99999 is exactly 4.9999

On physics, if that same number represents a measure, for example:

4.99999 meters is practically equal to 5 meters.

Answer: The length of First piece = 6

The length of second piece = 18

The length of third piece = 30  

Step-by-step explanation:

Given data,

A 54-inch board is to be cut into three pieces.

so that the second piece is 3 times as long as the first piece and the third piece is 5 times as long as the first piece.

So, we can write,

Let us assume, first piece is represented by = x

Then,

second piece is 3 times as long as the first piece

So, we can write,

second piece is represented by = 3 ( first piece )

second piece is represented by = 3x

Then,

third piece is 5 times as long as the first piece

So, we can write,

third piece is represented by = 5 ( first piece )

third piece is represented by = 5x

So, we can find the all 3 pieces length,

we can solve it :
combine all three pieces = x + 3x + 5x

length of all three pieces = x + 8x

                                          = 9x

 Total board is to be cut into three pieces = 54

Hence,

                         9 x = 54

                          x = 54/9

                          x = 6

Now we know that the base length, x, is equal to 6.

From there, we can find the length of the all three pieces is :

The length of First piece = x = 6

The length of second piece = 3x

                                         = 3(6)

                                         = 18

The length of third piece = 5x

                                         = 5(6)

                                         = 30

Therefore,

The length of First piece = 6

The length of second piece = 18

The length of third piece = 30

The temperature outside at night is 2 degrees.

One degree Celsius, for instance, is one-hundredth of the temperature difference between the point at which water changes state from solid to liquid to its gaseous stage. A degree can be defined as a fixed change in temperature measured against a specific scale.

Let's say the temperature outside is x.

Now, the initial temperature was - 17 degrees, then it rises to 9 degrees during the day before it drops 10 degrees at night.

So,

x = - 17 degrees

The temperature rises by 9 degrees.

Then,

x = - 17 degrees + 9 degrees

x = - 8 degrees

The temperature drops 10 degrees at night.

Then,

x = -8 degrees + 10 degrees

x = 2 degrees

Apply the absolute rule:

[tex]\textsf{If $|u| > a$, $a > 0$ \;then \;$u > a$ \;or \;$u < -a$}.[/tex]

Therefore:

[tex]\textsf{Case 1}: \quad |2x-1|-2 > 3[/tex]

[tex]\textsf{Case 2}: \quad |2x-1|-2 < -3[/tex]

Solve each case independently.

Isolate the absolute value on one side of the equation:

[tex]\begin{aligned}\implies |2x-1|-2& > 3\\\implies |2x-1| & > 5 \end{aligned}[/tex]

Apply the absolute rule:

Therefore, x < -2 or x > 3.

Isolate the absolute value on one side of the equation:

[tex]\begin{aligned}\implies |2x-1|-2& < -3\\\implies |2x-1| & < -1 \end{aligned}[/tex]

As an absolute value cannot be less than zero, there is no solution for x∈R.

If the inverse of f exists, it is represented by f⁻¹ and exists only if f is a bijective function.

The inverse of the function is f⁻¹ = - (x² - 3/2)

Domain is 3/2 to positive infinity

Range is 0 to positive infinity.

The inverse function of a function f is a function that reverses the operation of f. The inverse of f exists if and only if f is bijective, and it is denoted by f⁻¹ if it exists.

A function's inverse is not always a function. To ensure that the inverse function is also a function, the original function must be a one-to-one function. A one-to-one function is one in which each second element corresponds to exactly one first element.

Let the given function be f(x) = √-2x+3

y = √-2x+3

simplifying the value of x, we get

x = √-2x+3

x² = -2y + 3

simplifying the above equation, we get

x² - 3 = -2y

y = - (x² - 3/2)

Therefore, the inverse function be f⁻¹ = - (x² - 3/2)

Domain is 3/2 to positive infinity because a negative number cannot be square-rooted.

Range is 0 to positive infinity.

f⁻¹ = - (x² - 3/2)

The domain of the inverse is negative infinity to positive infinity, which is not a mirror image of the range of the original equation.

Anything squared is a positive number or zero.

The minimum value of the range is

f⁻¹ = - (x² - 3/2)

f⁻¹ = -(-3/2)

f⁻¹ = 3/2

The range of the inverse is 3/2 to positive infinity, a mirror of the domain of the original equation.

If a student population of 1200 was estimated to increase by 15% in the next five years but the population actually increased by 20%, then the most estimated and actual student populations are equal to 1380 and 1440 students respectively, and the percent error is equal to 4.2%.

The estimated and actual student populations can be calculated as follows,

Estimated increase = 15% = 15 / 100 = 0.15

Initial population = 1200

0.15 × 1200 = 180

Estimated population in the next five years = 1200 + 180 = 1380

Actual increase = 20% = 20 / 100 = 0.2

Initial population = 1200

0.2 × 1200 = 240

Actual population in the next five years = 1200 + 240 = 1440

We can find the percentage error as follows,

percentage error = [(actual value - estimated value) / actual value] × 100

percentage error = [(1440 - 1380) / 1440] × 100

percentage error = [60 / 1440] × 100

percentage error = 0.042 × 100 = 4.2%
