Answer
Explanation:
Step1: Solve (\tan x = 0)
We know that (\tan x=\frac{\sin x}{\cos x}). When (\tan x = 0), (\sin x=0) and (\cos x\neq0). On the interval ([0,2\pi)), (\sin x = 0) when (x = 0,\pi).
Step2: Solve (\cot x+1 = 0)
Since (\cot x=\frac{\cos x}{\sin x}), the equation (\cot x+1 = 0) can be rewritten as (\frac{\cos x}{\sin x}+1 = 0), or (\frac{\cos x+\sin x}{\sin x}=0). This implies (\cos x+\sin x = 0) ((\sin x\neq0)). Dividing both sides by (\cos x) (assuming (\cos x\neq0)), we get (1+\tan x = 0), so (\tan x=- 1). On the interval ([0,2\pi)), (\tan x=-1) when (x=\frac{3\pi}{4},\frac{7\pi}{4}).
Answer:
(x = 0,\frac{3\pi}{7},\pi,\frac{7\pi}{4})
