Therefore, tan (−θ) = −tan θ. tan θ is an odd function. Polar coördinates. We can specify the position of a point P by giving its distance r from the origin and the angle θ that r makes with the x-axis. Those are called the polar coördinates of P ... WebJul 19, 2013 · We know that tan2θ = 1/ cot2θ , hence applying A.M ≥ G.M logic, we get A.M of given equation = (4 tan2θ + 9 cot2θ) / 2 …. (1) G.M of given equation = √ (4 tan2θ . 9 cot2θ ) = √ 4 * 9 # ( tan2θ and cot2θ inverse of each other, so tan x cot =1) = √ 36 = 6 …. (2) Now, we know that A.M ≥ G. M From equations (1) and (2) above we get, incentives or things that arouse
