Web$\begingroup$ Hi , thanks! the question was : did the funtion tan(x) ,cot(x) has a symmetry axis , I tried to look at the function graph and see if there is a symmetry, i think there isn't one but I'm not sure how to get the full picture, and a good explanation why this is true without relying only on the function graph $\endgroup$ – Dima Shifrin WebIn 0 ≤ x ≤ 2π; Solution are x = 71.60,251.60,1350,3150 Explanation: tanx −2−3cotx = 0 or tanx− 2− tanx3 = 0 or tan2x− 2tanx−3 = 0 or (tanx −3)(tanx+ 1) = 0; ∴ tanx− 3 = 0 or tanx+ 1 = 0;eithertanx = 3 or tanx = −1 ∴ x = tan−1(3) = 71.60(1dp),(180+71.6) = 251.60 ...

Webtan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following then somehow it says therefore tan^2-1 = sec^2 so it replaces the entire first argument with sec^2, completely ignoring that 1 we were supposed to deduct from tan. blumenbörse rothrist teamclerk of miami dade courtWebprove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) prove\:\cot(2x)=\frac{1-\tan^2(x)}{2\tan(x)} prove\:\csc(2x)=\frac{\sec(x)}{2\sin(x)} prove\:\frac{\sin(3x)+\sin(7x ... clerk of martin countyWebHere we use the formula of cotangent which is cot x = (cos x) / (sin x) and the formula of tangent which is tan x = (sin x)/ (cos x). Also, csc x = 1/sin x.
