Homework Statement
Find the derivative of (x^2)(sinx)(tanx)
Homework Equations
f(x+y)(d/dx)=(x)(y)d/dx+(y)(x)d/dx
That's for differentiating with 2 terms. With 3, I haven't done it yet.
The Attempt at a Solution
x^2(sinx)(sec^2x)+tanx(sinx)2x+x^2(tanx)(cosx)
x^2(sinx/1)(1/cos^2x)+sinx/cosx)(sinx/1)(2x)+x^2(sinx/cosx)(cosx/a)
sinx/cosx(x^2/cos^2x+2xsinx+x^2cosx)
Another attempt was
2xsinxtanx
Which one do you guys think is right. It may be neither of them.
