Question 301839
i need to differentiate y = (Sqrt x^2 +4) sinx
--------------
Form: If f = gh, f' = gh'+hg'
-------------------------------------
y' = (sqrt(x^2+4)(cos(x)) + (sin(x))(1/2)(2x)/sqrt(x^2+4)
---
y' = (sqrt(x^2+4)(cos(x)) + (sin(x))(x/sqrt(x^2+4))
=======================================================
Cheers,
