Prove that y = 4sinθ/(2 cosθ) θ is an a increasing function of θ in 0, π /2 asked in Derivatives by Beepin ( 587k points) application of derivative If sinθ = A, find cos(π/2θ) (using trigonometric identities to fine the value) Get the answers you need, now! Proof 2 Sine to Cosine Step 1 We can use the result in proof 1 to prove the second cofunction identityIf we substitute π/2 – v in the first formula, we obtain cos π/2 – (π/2 – v) = sin (π/2 – v) Step 2 Evaluate the value trigonometric functions that are solvable cos (v) = sin (π/2 – v)
