text: 1-sin^2x/1sinx=cscx+1/cscx? prove this someone please, i am having the worst trouble with this problem did you leave out a minus sign between the 1 and the sinx on the left?  if so,  factor the numerator on the left and cancel the denominator: (1-sinx)(1+sinx)/(1-sinx) becomes 1 + sinx  on the right, split (cscx + 1)/cscx into 2 fractions: cscx/cscx + 1/cscx  cscx/cscx is just 1, and 1/cscx is sinx  so you get 1 + sinx = 1 + sinx  hope that makes sense.
