Question

Express sin θ in terms of cot θ, where θ is an acute angle.

• A. $$\frac{1}{\sqrt{(1+cot^2\theta)}}$$
• B. $$\sqrt{(1+cot^2\theta)}$$
• C. $$\frac{1}{(1+cot^2\theta)}$$
• D. $$(1+cot^2\theta)$$

Answer 1

Answer:

$$\frac{1}{\sqrt{(1+cot^2\theta)}}$$

sin²θ + cos²θ = 1

sin θ = 1 / √(1 + cot²θ)
