RoundBear Posted May 14, 2007 Report Share Posted May 14, 2007 I have some problems that I can't seem to figure out. Simplify: csc(x) cos^2(x)/ 1+csc(x) I can't seem to simplify it. anyone have any hints? Link to comment Share on other sites More sharing options...

Siege Posted May 15, 2007 Report Share Posted May 15, 2007 I just deleted my post but.... I think I was righter with the .5 Cos ^ 2 Cscs cancel leaving you with Cos^2 / 1 + 1 Link to comment Share on other sites More sharing options...

I think I was righter with the .5 Cos ^ 2 Cscs cancel leaving you with Cos^2 / 1 + 1 Steps: csc(x) cos^2(x)/ 1+csc(x) (1/sinx)(cos^2x) / [1+(1/sinx)] =(cos^2x/sinx)/[(sinx+1)/sinx)] - First part, multiply. Cos on top, sin on bottom. 2nd part, common base. =(Cos^2x/sinx)x(sinx/sinx+1) -Multiply by reciprocal. First sinx on bottom, cancels 2nd sinx (which is on top) =Cos^2/(Sinx+1) Link to comment Share on other sites More sharing options...
