cos(θ)=-sin(θ)

Solution

cos (θ) = - sin (θ)

Solution

θ = \frac{3 π}{4} + πn

+1

Solution steps

cos (θ) = - sin (θ)

Rewrite using trig identities

- tan (θ) = 1

Divide both sides by

- 1

tan (θ) = - 1

General solutions for

tan (θ) = - 1

θ = \frac{3 π}{4} + πn

sqrt(2)csc(x)+2=4

2 csc (x) + 2 = 4

sec^2(θ)+5sec(θ)-6=0

sec^{2} (θ) + 5 sec (θ) - 6 = 0

cos (x) = 0.75

cos (x) = 0.76

0 = 4 cos (2 x)
