Hi coolbeans,I need to find the f'(x) when f(x)= A/B+C (ex)
so I used the quotient rule to get:
(B+Cex)(1) - A(B+Cex)/(B+Cex)2
is this right so far? and if it is, how do I simplify it more?
First off, you're applying the chain rule, which has multiplication instead of addition.this still makes no sense! after I applied the chain rule I got
-1A(B+Cex)-2 + d/dx (AB+ACex)
the part I don't get is how I'm supposed to take the derivative of the variables. do I just treat them like x and say they're equal to one?
First off, you're applying the chain rule, which has multiplication instead of addition.
So you should have:
-1A(B+Cex)-2 * d/dx (AB+ACex)
Then you have these A, B, and C, which are constants, not variables.
You should treat them the same as if they would read for instance 2, 3, respectively 4.
What would be d/dx (2*3+2*4*ex)?
When you have that, you should replace any occurrences of 2, 3, and 4 again by A, B, and C respectively.
