Several Mathematics problems?
If anybody would like to tell me the solutions and methods for these math problems I would be very grateful.1. If sinx= 5/13 , and pi/2 < x < pi , then sin 2x= ???2. This one might be confusing.. (10/(x+1)) / (.5 + (3/(x+1)))3. simplify (x+2) +( (x^29x22)/(x^2121) )SOLVE4. 2cos^2(x)5cosx3=05. sin2x=cosx6. simplify ((x+y)/x) / (x^1) + (y^1) Thanks!
