At x = 270°, sinx = −1. • The graph of sinx crosses the x-axis three times in the interval 0° ≤ x ≤ 360°. At x = 0°, 180°, and 360°, sinx = 0. • The graph of sinx is the same shape as the graph cosx / (1 - tan x) + sin x/(1 - cot x) = sin x + cos x Express tan^-1(cosx/(1 - sinx)), - π/2 < x < π/2 in the simplest form. asked Oct 4, 2019 in Mathematics by Radhika01 ( 63.1k points) inverse trigonometric functions substitute tan(x) = sin(x)/cos(x), multiply numerator and denominator by cos(x) and then include the first cos(x) term to that fraction by making one fraction.

Substitute these values into equation (1) tan x = (hyp * sin x) / (hyp * cos x) Cancel out the common hyp term, and you have.

substitute tan(x) = sin(x)/cos(x), multiply numerator and denominator by cos(x) and then include the first cos(x) term to that fraction by making one fraction.

tan(x) + 1 = 0. You have to be careful though, because to avoid division by zero we now have to assume x â Ï /2, but x = Ï /2 isn't a solution to . sin(x) + cos(x) = 0. anyway, so there's no problem.
