sin(x)=3cos(x)

sin (x) = 3 cos (x)

x = 1.24904 \dots + πn

Solution steps

sin (x) = 3 cos (x)

Rewrite using trig identities

tan (x) = 3

Apply trig inverse properties

x = arctan (3) + πn

Show solutions in decimal form

x = 1.24904 \dots + πn

2 sin^{2} (x) - 3 cos (x) = 3

4 cos (x) = 3 + 8 cos (x)

sin^{2} (θ) - 3 sin (θ) = 0

cos^{2} (x) = \frac{1}{5}

- 3 cos (2 θ) + 5 = 7 sin (θ) + 5
