For each of the following equations, solve for (a) all degree solutions and (b) θ if 0 ° θ < 360 ° . Do not use a calculator.

2 cos 2 θ + 11 cos θ = 5

Expert Solution

(a)

To determine

To solve:

For θ all degree solution

Explanation of Solution

Given:

2cos2θ+11cosθ=5

Calculation:

We are given 2cos2θ+11cosθ=5

We will set each factor to 0 and solve for x

2cos2θ+11cosθ=5{Given}2cos2θ+11cosθ+5=0{Add -5 both sides}(2cosθ+1)(cosθ+5)=0{Factor}2cosθ

Expert Solution

(b)

To determine

To solve:

For θ between 0x<360
