WebMar 26, 2016 · Solve tan 2 x = tan x for the values of x such that 0 x < 2. Move the term on the right to the left by subtracting it from both sides. tan 2 x – tan x = 0 Don’t divide through by tan x. You’ll lose solutions. Factor out tan x. tan x (tan x – 1) = 0 Set each of the two factors equal to 0. tan x = 0 or tan x – 1 = 0 WebAnd sometimes you'll be given an equation which is not an identity. If you plug a value in where the two sides happen to be equal, such as π/4 for the (false) identity sin(x) = cos(x), you could fool yourself into thinking that a mere equation is an identity. You'll have shot yourself in the foot. So let's not do that. tsgt promotion cycle
