Numerical value of one trigonometric function

Postby Guest » Sun Oct 27, 2013 12:35 pm

My PreCalc teacher assigned a bunch of trig identity problems for homework, and doesn't teach very well. Can anyone provide assistance finding a numerical value of one trig function of 2tan(x)sin(x)+2cos(x)=csc(x)... and a few other problems if possible.
Thank you!
