cos(x)=3sin(x)

cos (x) = 3 sin (x)

x = 0.32175 \dots + πn

Solution steps

cos (x) = 3 sin (x)

Rewrite using trig identities

3 tan (x) = 1

Divide both sides by

3

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

Apply trig inverse properties

x = arctan (\frac{1}{3}) + πn

Show solutions in decimal form

x = 0.32175 \dots + πn

tan (23 θ) + cot (23 θ) = \frac{4}{3}

tan^{2} (x) + 1 = sec (x)

\frac{3}{16} = 1 (cos (0)) (cos (3 0^{\circ})) (cos (x - 3 0^{\circ}))

cos (x) - 2 = - 5 + 2

1 + sec^{2} (x) = tan (x)
