Homework Statement


∂z/∂x of ycos(xz)+(4xy)-2z^2x^3=5x[/B]

Homework Equations


n/a

The Attempt at a Solution


∂z/∂x=(5+yz-4y+6z^2x^2)/(-yxsin(xz)-4zx^3)[/B]

Is this correct? Just trying to make sure that's the correct answer. I appreciate the help. I can post my work if need be. Thanks

Close, but check your work. There is at least a sine term missing in the numerator. Better yet, show your work.
 
-y*sin(xz)*(z+x(∂z/∂x))+4y-4zx^3(∂z/∂x)-6z^2x^2 = 5

This is what I have before rearranging and factoring for ∂z/∂x

That looks good. If you carefully do the algebra solving for ##\frac{\partial z}{\partial x}## you should be OK.
 
(5+yzsin(xz)-4y+6z^2x^2)/(-yxsin(xz)-4zx^3) = ∂z/∂x

Pretty sure this is right. Just messed up on my algebra. Thank you so much. The internet is great.
 
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...
