15cos(x)=0

15 cos (x) = 0

x = \frac{π}{2} + 2 πn, x = \frac{3 π}{2} + 2 πn

Solution steps

15 cos (x) = 0

Divide both sides by

15

cos (x) = 0

General solutions for

cos (x) = 0

x = \frac{π}{2} + 2 πn, x = \frac{3 π}{2} + 2 πn

sin (\frac{π}{2} - x) = cos^{2} (x)

sin (θ) = \frac{π}{3}

tan (x) sin (x) + sin (- x) = 0, 0 \leq x \leq 2 π

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

cos (x + \frac{3 π}{4}) - cos (x - \frac{3 π}{4}) = 0
