Question

Hey there! can anyone explain derivatives of arctrig function to me? for example, the derivative of xarctan(x)?
Thanks!

Answer 1

do you mean arctan(x)?

Answer 2

well, yeah, i guess, if i know how to do arctan(x), i can use product rule to do xarctan(x)

Answer 3

\[y=\tan^{-1} (x) \Rightarrow \tan y = x\] so we can use implicit differentiation to get what we're after... dy/dx

Answer 4

oh! that makes so much more sense! Thank you!

Answer 5

This may help too!

Answer 6

oh, wow, thank you!
