solvefor x,cos(x)=-sin(x)

solve for

x, cos (x) = - sin (x)

x = \frac{3 π}{4} + πn

Solution steps

cos (x) = - sin (x)

Rewrite using trig identities

- tan (x) = 1

Divide both sides by

- 1

tan (x) = - 1

General solutions for

tan (x) = - 1

x = \frac{3 π}{4} + πn

csc (x) - 2 sin (x) = 0

sin (2 x + 11 0^{\circ}) + sin (2 x - 1 0^{\circ}) = \frac{1}{2}

6 cot^{2} (x) - 18 = 0

(2 sin (θ) - 3) (sin (θ) - 1) = 0

20 sin^{2} (x) + cos (x) - 19 = 0
