Hey guys working on a problem for an assignment but my algebra is weak regrettably and I need some assistance.(adsbygoogle = window.adsbygoogle || []).push({});

Note:: I left the x and dx out for clarity.

1. The problem statement, all variables and given/known data

int csc/cot^{2}

3. The attempt at a solution

int csc x/cot^{2}x dx= int csc/cos^{2}/sin^{2}

= int cscsin^{2}/cos^{2}

= int 1/sin * sin^{2}/cos^{2}

= int sin/cos^{2}

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/u^{2}du then i just replace that u with x

Correct ?
