4cos+sinx-cosx/ sin^2x
How do I start? I don't think I can use u substitution:/
I tried canceling the sinx bit I'm still left with sinx at the bottom.
Notice that skeeter did a completely different problem from sakonpure6 and Soroban! dreamd7358, please use parentheses to make you meaning clear. skeeter assumed you meant what you actually wrote: 4cos+sinx-cosx/ sin^2x= 4cos(x)+ sin(x)- (cos(x)/sin^2(x)) while sakonpure6 and Soroban guess that you really meant (4 cos(x)+ sin(x)- cos(x))/sin^2(x).
(Althoug we all had to guess that your initial "4cos+ sinx" meant "4cos(x)+ sin(x)"!
