solvefor θ,a(1+cos(θ))=0

solve for

θ, a (1 + cos (θ)) = 0

θ = π + 2 πn

Solution steps

a (1 + cos (θ)) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

1 + cos (θ) = 0

Move

1

to the right side

cos (θ) = - 1

General solutions for

cos (θ) = - 1

θ = π + 2 πn

cos (θ) = \frac{1}{21}

- \frac{1}{2} = cos (x)

3 sin (x) = sin (3 x)

tan (x) + 3 = 1 + 3 cot (x)

tan (u) - cot (u) = 2
