Question 1060448

 Find the exact value of the trigonometric function given that sin u = 5/13 and cos v = -3/5 (Both are in Quadrant II.) sin (u + v)
<pre>Problem # 1060297 "asked" for sec (v - u). That answer was given to you. Why can't you follow the same steps to obtain sin (u + v)?
Why do you want someone to do everything for you? You have to make an effort, and give someone else a chance to get their problem solved. 
Don't you think you're being UNFAIR?
