WebNov 9, 2015 · So Knowing Sin 0 = 0 means it must include the Opp in the Numerator ( as the angle goes to 0 - the Opp does, and you know nothing about the Adj and Hyp) - same for Tan (0) = Sin /Cos = again Opposite must be in the numerator, and thus Sin must be in the Numerator.. I know this is weird but there is no other solution. WebWell, sin of 90 degrees means that you are trying to find the opposite over hypotenuse of a triangle with a measure of 90 degrees. But the opposite side to a 90 degree angle IS the hypotenuse. ... 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 ...

WebWe wish to prove the following trig identity: 1 − tan (θ) cos (θ) + 1 − cot (θ) sin (θ) = sin (θ) + cos (θ) a. First, begin by rewriting each of the trig functions on the left hand side of the equality in terms of only sines and cosines (for example, rewrite tan (x) as cos (x) sin (x) ): 1 − tan (θ) cos (θ) + 1 − cot (θ) sin (θ) = b. Rewrite your expression from part (a) by ...
