Solution

x = \frac{3 π}{4} + πn

+1

Solution steps

sin (x) = - cos (x)

Rewrite using trig identities

tan (x) = - 1

General solutions for

tan (x) = - 1

x = \frac{3 π}{4} + πn

Popular Examples

tan(x)= 1/(sqrt(3))

tan (x) = \frac{1}{3}

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

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

csc^{2} (x) - 2 = 0

2sin^2(x)+cos(x)-1=0

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

sin(4x)=-2sin(2x)

sin (4 x) = - 2 sin (2 x)
