[tex]\int\left(\frac{dx}{dt}\right)^{2}dt=?[/tex]

I even have the answer my brain is just refusing to play along though and I just can't picture how to work it out properly at the moment.

Thanks!

try writing it as

[tex]\int \frac{dx}{dt} \frac{dx}{dt} dt[/tex]

instead.

[tex]\int \frac{dx}{dt} \frac{dx}{dt} dt[/tex]

instead.

Thanks for your reply.try writing it as

[tex]\int \frac{dx}{dt} \frac{dx}{dt} dt[/tex]

instead.

In that case I don't have brain freeze I just don't know. I just want to cancel the dt's but then

I get

[tex]\int \frac{dx}{dt}dx[/tex]

which I don't know how to handle.
