f(t)=8(sqrt t)-(8)/(sqrt t)

Question

Differentiate the following function. 
 
f(t)=8(sqrt t)-(8)/(sqrt t)

nowhereman · Answer

These are just the basic differentiation rules. Do you know the derivative of the square root?

anonymous · Answer

Yea so far i have 8(1/2 t^-1/2)-8(/1-2 t ^-1/2) now im stuck on that location

nowhereman · Answer

This is really hard to read.
When you have $1/\sqrt t$ you need to deal with it like $t^{-\frac{1}{2}}$ so you'll get $-\frac{1}{2} t^{-\frac{3}{2}}$

im not understanding what you are writing theres too many //[[{{

nowhereman · Answer

Then you should turn on javascript, so that it can get rendered as latex.

anonymous · Answer

Yeah, make sure you have javascript on and then it'll look alot better :P

i am but its taking to long

anonymous · Answer

$$4/\sqrt{t} + 4/t^{3/2}$$

anonymous · Answer

ok thanks SmRoberts..im still trying to figure out where i got wrong and my java is not working at the moment

anonymous · Answer

happy to help

anonymous · Answer

df(t)/dt=d/dt[8(sqrt t)-(8)/(sqrt t)]
            =8(1/2 t^-1/2)+8(1/2 t ^-3/2)
             =(4 t^-1/2)+(4 t ^-3/2) answer
