there are a couple calculus problems I'm not sure I did right, and it is an important assignment:
1. find dy/dx if y=((3x)^(1/2))/(2x-1)
and
2. Differentiate: y=x^(1-x)
3. Find the general solution of the differential equation: xcosy + tany(dy/dx)= 0
Thanks, I've answered all of these but not sure if I did them correctly! help on these problems would be greatly appreciated!
