<u>Trigonometric Identities</u>

<u>Trigonometric ratios</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Using the trig ratio formulas for cosine and sine:
Therefore, using the trig identities and ratios:

All you do is add up all your sides! So if your shape has 4+4+5+5 = 18. All you do is add them up!
Answer:

Step-by-step explanation:
We are given the integral of:

First, we can use a property to separate a constant out of integrand:

Next, expand the expression (integrand):

Since
then it can be simplified to:

Recall the formula:

For
, we need to convert to another identity since the integrand does not have a default or specific integration formula. We know that:

We can solve for
which is:

Therefore, we can write new integral as:

Evaluate each integral, applying the integration formula:

Then add all these boxed integrated together then we'll get:

Expand 4 in the expression:

Therefore, the answer is:

Answer: 
Step-by-step explanation:
Plot the vertices of the rectangle on a coordinate plane (Observe the figure attached where the rectangle is identified as ABCD).
The area of a rectangle can be calculated with this formula:

Where "l" is the lenght and "w" is the width.
In order to find the lenght and the width, you can use the formula for calculate the distance between two points:

Knowing the coordinates of the vertices, you get:

Therefore, substituting values into the formula
, you get that the area of the rectangle is:
