Hey guys working on a problem for an assignment but my algebra is weak regrettably and I need some assistance. Note:: I left the x and dx out for clarity. 1. The problem statement, all variables and given/known data int csc/cot2 3. The attempt at a solution int csc x/cot2x dx= int csc/cos2/sin2 = int cscsin2/cos2 = int 1/sin * sin2/cos2 = int sin/cos2 Is the algebra at the equal signs correct? If not what went wrong? Then I make a u -substitution u = cos x then du = -sinx dx then dx = - du/sinx that makes - int 1/u2du then i just replace that u with x Correct ?
