solvefor x,cos(x+y)=0

solve for

x, cos (x + y) = 0

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

Solution steps

cos (x + y) = 0

General solutions for

cos (x + y) = 0

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

Solve

x + y = \frac{π}{2} + 2 πn : x = \frac{π}{2} + 2 πn - y

Solve

x + y = \frac{3 π}{2} + 2 πn : x = \frac{3 π}{2} + 2 πn - y

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

θ, sin (2 θ) = \frac{1}{2}

sin (x) + cos (x) = \frac{6}{2}

2 cos^{2} (\frac{x}{3}) + 3 sin (\frac{x}{3}) - 3 = 0

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

sec^{2} (x) - 3 = 0
