Question

write expression for sin 3 theta and Cos 3 theta​

Answer 1

Answer:

\sin^3(\theta) = \frac{3 \sin (\theta) - \sin \left( 3 \theta \right) }{4},\quad \cos^3 (\theta) = \frac{\cos(3\theta) + 3 \cos (\theta)}{4}. sin3(θ)=43sin(θ)−sin(3θ),cos3(θ)=4cos(3θ)+3cos(θ). "Dollar thirty is equal to four dollar thirty minus three dollar."

Answer 2

Step-by-step explanation:

sin3(θ)= 3sin(θ) - 4sin(θ)³

cos3(θ)=4cos(θ)³+3cos(θ).
