2 cos (θ) = - 2

Divide both sides by

2

cos (θ) = - 1

General solutions for

cos (θ) = - 1

θ = π + 2 πn

Popular Examples

solvefor x,cos(2x)+2/(cos(2x))+3=0 solve for

x, cos (2 x) + \frac{2}{cos ( 2 x )} + 3 = 0

sin(t)=(250)/(sqrt(250^2+300^2))

sin (t) = \frac{250}{25 0 ^{2} + 30 0 ^{2}}

0 = sin (13 x)

cos (a) = \frac{9}{41}

sin^2(θ)-2=cos^2(θ)

sin^{2} (θ) - 2 = cos^{2} (θ)
