Csc θ + sin −θ cos2 θ sin θ
WebMay 8, 2024 · Step-by-step explanation: There is a trigonometric identity that states that: sin²θ + cos²θ = 1. Now, for the given we have: (sin²θ + cos²θ) (sin θ + cos θ) Applying the above identity, we would find that the expression becomes: (1) (sin θ + cos θ) which is equal to sin θ + cos θ. Hope this helps :) Advertisement. WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations.
