Math Help - another differentiation

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

I assume that csc means 'cosec', in which case,



So its derivative is
