WebTheorem 3: If x and y are not odd-multiples of \frac {π} {2} , then \tan {x} = \tan {y} implies x = nπ + y, where n ∈ Z. Proof: We have, \tan {x} = \tan {y} ⇒ \tan {x} – \tan {y} = 0 ⇒ \frac {\sin {x}} {\cos {x}} – \frac {\sin {y}} {\cos … WebTheorem 3: Prove that if x and y are not odd multiple of π/2, then tan x = tan y implies x = nπ + y, where n ∈ Z. Proof: Similarly, to find the solution of equations involving tan x or other functions, we can use the conversion of trigonometric equations. In other words, if tan x = tan y then; sin x cos y – sin y cos x = 0
