Hi Byron,

My symbolic math software tells me that the integral of that equation is:

LN((2·x\^2 + 1)·ABS(x))/4

(strange! I would have expected a rational polyonom..)

Btw - I use “derive for windows” from texas instruments for such math things.. It is not as powerfull as mathlab but much easier to learn and work with.

TI has a demo of it on their webpage. Give it a try.

Having taken Calculus over 35 years ago and did pretty well, I am now a bit stumped in solving this. I have factered 1/4 to the left of the integrand, and let u=2x\^3+1, and then get du/dx=6x\^2, then substitute back in but get stumped at that point.

Really would appreciate some help on this one.

Byron
