tan 2 (t) + 1 = sec 2 (t) 1 + cot 2 (t) = csc 2 (t) Advertisement. Note that the three identities above all involve squaring and the number 1. You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.

2015年5月9日 · #tan^2x-1=(tanx+1)(tanx-1)# Now, substitute this in the original equation. #(tanx+1)(tanx-1)=0# When the product of any number of terms is equal to #0#, one of the terms must be equal to #0# at any time. To solve for #x#, set both multiplied terms equal to #0#. #{(tanx+1=0),(tanx-1=0):}# Solve for both. #{(tanx=-1),(tanx=1):}# These are common ...

In Trigonometry, different types of problems can be solved using trigonometry formulas. These problems may include trigonometric ratios (sin, cos, tan, sec, cosec and cot), Pythagorean identities, product identities, etc. Some formulas including the sign of ratios in different quadrants, involving co-function identities (shifting angles), sum & difference identities, double angle …
