Find the ratio of the fluxion of x to the fluxion of 1/x using Newton's synthetic method of fluxions.
Relevant Equations
None.
I was asked to find the ratio of the fluxion of x to the fluxion of 1/x using Newton's synthetic method of fluxions. I do not understand how to do this.

I believe you. But PF guidelines require you post your own attempt before assistance is allowwed.
So: what are we talking about ? What is a fluxion a la Newton (sounds like a recipe :smile: ) and how does one calculate it ?

Thanks for your belief :)
A fluxion of the quantity x (which is dependent on time) is the speed at which speed increases.

Essentially it seems to be the derivative.
 
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...
