cos(x+pi/3)+cos(x-pi/3)=1

cos (x + \frac{π}{3}) + cos (x - \frac{π}{3}) = 1

x = 2 πn

Solution steps

cos (x + \frac{π}{3}) + cos (x - \frac{π}{3}) = 1

Rewrite using trig identities

cos (x) = 1

General solutions for

cos (x) = 1

x = 0 + 2 πn

Solve

x = 0 + 2 πn : x = 2 πn

x = 2 πn

5 tan^{2} (x) + 3 tan (x) = 0

sin (2 x) + 4 = 3 sin (2 x) - 5

3 cos^{2} (x) - 1 = 0

- cos (2 x) + cos (x) = 0

x, cos (x) + sin (y) = 1
