Default Trigonometry- Solve. tan(x)csc^2(x)cos(x)=0?

For these problems you must get simplify it down to something, for example, sin(x)=1 and then you must find where on the unit circle sin(x) equals 1 which is at pi/2 so thats the answer. So if anyone could at least get me the simplified equation and how they got there I could finish the problem. THANKS!
