sorry to bother you alot i tried to solve this one, but im not sure about my steps. the problem is 1/csc(1-5x^2) u=(1-5x^2) f(u)=1/csc u im not sure if i can put it like this. d/du*1/csc u * d/dx (1-5x^2) thanks

the problem is 1/csc(1-5x^2) u=(1-5x^2) f(u)=1/csc u im not sure if i can put it like this. I dont know what is "csc()" but it seems correct
