differentiate this, i need help

[afcwestwarrior]

y=ex(x is suppost to be smaller and on the top right of e)/x squared

i a suppost to differentiate this, well i wrote -2ex/x cubed+ ex/ x sq.

now u probabl might be confused by the way i wrote it since i dont know how to put the right things for my problems,

well i set up the problem how do i figure out the answer,

i know the answer but how do i figure it out

Is this what you are getting at y = ex/x2?

Would it help if you rewrite it as a product rule:
ex.x-2

This is correct.

[Gib Z]

i know the answer but how do i figure it out

y=\frac{e^x}{x^2}
Let u=e^x and v=x^2.

By the quotient rule, the derivative is \frac{u'v-v'u}{v^2}

I must've skipped over this, and so didn't notice that you wanted to know how to get the answer!!

Well, anyway, now you've got two ways; using the product rule as shown by ranger, or the quotient rule given by Gib Z.
