2cos(x)-3=-5

Solution

2 cos (x) - 3 = - 5

Solution

x = π + 2 πn

+1

Solution steps

2 cos (x) - 3 = - 5

Move

3

to the right side

2 cos (x) = - 2

Divide both sides by

2

cos (x) = - 1

General solutions for

cos (x) = - 1

x = π + 2 πn

Popular Examples

sin(3θ)-sin(θ)=cos(2θ)

sin (3 θ) - sin (θ) = cos (2 θ)

2sin(x)+(2-sqrt(3))=sqrt(3)csc(x)

2 sin (x) + (2 - 3) = 3 csc (x)

tan^2(θ)+4sec(θ)=-5

tan^{2} (θ) + 4 sec (θ) = - 5

0 = tan (θ)

cos (θ) = \frac{4}{9}
