V = \sqrt{T/u}

Take the derivative respect to U. I'm having trouble with this.

\sqrt{T} * 1/\sqrt{u}


So would u look like this U^-(1/2)

since T is constant I'd leave it alone.

it would become -(1/2) * u^(-3/2)


Am I right or Am I wrong.

Right now you can re-write the equation as V= T^(1/2)*u^(-1/2)
effectively this is in the form of y=c*x^n (just to go back to familiar notation)
what is the generic formula for this? Your close, but your leaving out the constant...

So what would the answer be once you include it?
 


V= T^(1/2)*-(1/2) * u^(-3/2)
 


looks pretty good to me!
 


since T is a constant your answer is right
 


Thanks for the assistance!
 
Prove $$\int\limits_0^{\sqrt2/4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx = \frac{\pi^2}{8}.$$ Let $$I = \int\limits_0^{\sqrt 2 / 4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx. \tag{1}$$ The representation integral of ##\arcsin## is $$\arcsin u = \int\limits_{0}^{1} \frac{\mathrm dt}{\sqrt{1-t^2}}, \qquad 0 \leqslant u \leqslant 1.$$ Plugging identity above into ##(1)## with ##u...
