cos(x)=-sin(x)

Solution

cos (x) = - sin (x)

Solution

x = \frac{3 π}{4} + πn

+1

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

Popular Examples

4 cos^{2} (x) - 2 = 0

tan(3x)=sqrt(3)

tan (3 x) = 3

2 sin (x) = 0

sin (x) = \frac{- 1}{2}

cos(x)= 1/2 ,0<= x<= 2pi

cos (x) = \frac{1}{2}, 0 \leq x \leq 2 π
