4sin(x)-3cos(x)=0

4 sin (x) - 3 cos (x) = 0

x = 0.64350 \dots + πn

Solution steps

4 sin (x) - 3 cos (x) = 0

Rewrite using trig identities

4 tan (x) - 3 = 0

Move

3

to the right side

4 tan (x) = 3

Divide both sides by

4

tan (x) = \frac{3}{4}

Apply trig inverse properties

x = arctan (\frac{3}{4}) + πn

Show solutions in decimal form

x = 0.64350 \dots + πn

25 cos^{2} (3 x) + 10 cos (3 x) = 15

5 cos^{2} (x) = 6 sin (x)

sec^{2} (x) = 2 tan (x) + 4

- 4 cos (θ) = - sin^{2} (θ) + 1

2 sin^{2} (θ) + 3 sin (θ) = 0, 0 \leq θ < 2 π
