3=-3cos(θ)

Solution

3 = - 3 cos (θ)

Solution

θ = π + 2 πn

+1

Solution steps

3 = - 3 cos (θ)

Switch sides

- 3 cos (θ) = 3

Divide both sides by

- 3

cos (θ) = - 1

General solutions for

cos (θ) = - 1

θ = π + 2 πn

Popular Examples

2cos(θ)-sqrt(3)=0,0<= θ<= 2pi

2 cos (θ) - 3 = 0, 0 \leq θ \leq 2 π

-4sin(x)=cos^2(x)+1,0<= x<= 2pi

- 4 sin (x) = cos^{2} (x) + 1, 0 \leq x \leq 2 π

sqrt(3)sin(x)-3cos(x)=sqrt(3)

3 sin (x) - 3 cos (x) = 3

tan(2x)cos(2x)+cot(2x)sin(2x)=1

tan (2 x) cos (2 x) + cot (2 x) sin (2 x) = 1

sin^2(2x)-cos^2(2x)= 1/2

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