Answer:
Step-by-step explanation:
We want to solve the equation:
Over the interval [0, 2π).
First, notice that this is in quadratic form. So, to make things simpler, we can let <em>u</em> = cos(x). Substitute:
Rearrange:

Using the unit circle:
Answer:
n=−0.545455
Step-by-step explanation:
n(6.5)=−3+n
Simplify both sides of the equation.
n(6.5)=−3+n
6.5n=−3+n
6.5n=n−3
Subtract n from both sides.
6.5n−n=n−3−n
5.5n=−3
Divide both sides by 5.5.
5.5n
5.5
=
−3
5.5
