Web8 mei 2015 · sin x = cos x ⇒ tan x = 1 because clearly cos x ≠ 0 so we can divide both sides by cos x. Therefore, when x ∈ [ 0, 2 π], the solutions are x 1 = 1 4 π and x 2 = 5 4 π. Here is the figure. Edit: When you square both sides, you will make ( − sin x) 2 = ( sin x) 2. If − sin x = cos x, their squares are equal, which is a problem since they are not 0.
