Write down the values of sinx and cosx and (where possible) tanx when x is equal to. 0◦, 30◦, 45◦, 60◦, 90◦, 120◦, 135◦, 150◦, 180◦, 210◦, 225◦, 240◦, 270◦, ... Feb 9, 2016 ... sec(x) is related to cos(x) in the relation sec(x) = 1/cos(x). You are given tan(x) = 3 and cos(x)> 0. Note: 1st Quadrant : sin(x) > 0, The solutions to tan(x) - cot(x) = 0 are , where k is any odd integer. To solve this equation, we start by using the following trigonometric identities. h'(x) = cos(cas xttan x)·(cas x+ tan x) cas (cas x+ tax x)·(- sin ... 2sin x cos x=0. Sin, x=0. Cos x=0.
