How do I graph a sequence of partial sums on a TI-89/92/V200

I am doing exactly what this article is saying in order to try to graph
a sequence of partial sums. If I enter the syntax, given below, on the
home screen, it will list the first 25 terms of the partial sum. How do I
graph those terms using sequence mode?

You can just set u1 = the sum from k = 1 to n of 1/k. With sum for uppercase sigma, you would let u1(n) = sum(1/k, k, 1, n) You don't need to use the seq command.
 
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...
