# Solve this Trigonometric equation

I am not quite good at maths, so can you help me ?

$$\tan x + 2 \cot x - 3=0$$

What exactly do you want? $\tan (x) + 2 \cot(x)-3$? And what do you want to solve for? – Stefan Feb 13 '13 at 12:31

$$\tan{x}=\frac{1}{\cot{x}}.$$ $$\tan{x}+2 \cdot \frac{1}{\tan{x}}-3=0.$$ make a notation $t=\tan{x}.$
