Cot sin identity
WebStep 1: We can use the result in proof 1 to prove the second cofunction identity. If we substitute π/2 – v in the first formula, we obtain. Step 2: Evaluate the value trigonometric … Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle …
