Hey there, I've got a question thats been bugging me for ages...I have no idea how to start it! Differentiate tan(arcsin (1-x^2)^1/2) Any help will be appreciated, thanks!

Do you know the chain rule?
yes, but I dont see how I can use that here...
Let , and then, if necessary, let and use the chain rule twice.
So I would get something like f'(x)sec^2(f(x)) with f(x) being arcsin(1-x^2)^1/2 ?

Another approach might be to use: Then use the chain rule from there...
