There's no reason to take logs, it's just a product of functions, apply the product rule... or is it just that I'm misunderstanding the problem and it's ?
Okay, so I've tried doing this problem a million times and I can't seem to get the right answer. It seems fairly straight forward.
Here is the question:
If f(x)=6(sin(x))x , find f(3)
So this is what I've tried:
lny=6xlnsinx
(1/y)(y')=f'g+fg'
(1/y)(y')=(6)(lnsinx)+[(6x)((cosx)/(sinx))]
y'=[(6lnsin(x))+(6xcot(x))]*(6(sin(x))^x)
So I tried pluggin in 3 to the answer, but it does not give me the correct answer.
Am I doing something wrong?
(I've also tried with the assumption that lny=xln6sinx, but that didn't work either.
Thanx!
