Differentiation of a function

[elton_fan]

hi all
i need a derivative of this function f(t)=100t/2t+15


thanks a lot

You need to show us your attempt. Are you familiar with the quotient rule and so on?

FYI, you wrote

$$f(t)=\frac{100t}{2t}+15$$

Is that what you meant? If you meant to write

$$f(t)=\frac{100t}{2t+15}$$

then you need to use parentheses.

I'm almost certain he means the later, or the answer is pretty basic in fact it barely requires calculus.

$$f(t)=\frac{100t}{2t+15}$$

Have you tried the quotient rule? Please show working?
