Homework Statement



Given that y1(t) = t is a solution of t2y'' + ty' - y= 0 find all solutions.



The Attempt at a Solution


I already put it into mathbin asking somewhere else for help and it doesn't look like i can copy paste that syntax to here.

Could someone tell me if that is correct so far?
If so can you tell me where to go from there?
If not could you tell me where I made a mistake?

thank you.

After many hours of getting no where, I realized that the correct method to solve this problem is Reduction of order.

The answer is y2(t) = 1/t.
 
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...
