Answer:
Problem 1:
Problem 2:
Problem 3:
Step-by-step explanation:
Problem 1:
So we are going to use the following to help us:
So if we make those substitution into the first equation we get:
Factor the out:
The following is a Pythagorean Identity: .
We will apply this identity now:
This implies:
We don't need both because both of include points with radius 4.
Problem 2:
Factoring out from first two terms:
Apply the Pythagorean Identity I mentioned above from problem 1:
or if we factor out r:
r=0 is actually included in the other equation since when theta=0, r=0.
Problem 3:
Answer:
-
Step-by-step explanation:
cos90° - 2sin45° + 2tan180°
= 0 - ( 2 × ) + 2(0)
= 0 - + 0
= -
In your question where to explain how the raising a quotient to power is similar to raising a product to a power. Form me the best explanation to this statement is because the variable with a exponent of positive is equals to its exponent over its variable.
