The math help thread

I'm sure you can do better than that, being in this thread and all.

I can show you the series to derive all the digits of Pi if you want.

So, I finally understood how to do that question (though i messed that up for the assignment)

I'm suppose to rearrange the equation into
arcsin ((x-1)/(x+1))-2arctan(sqrt(x))-(pi/2)=0
then let f(x)=arcsin ((x-1)/(x+1))-2arctan(sqrt(x))-(pi/2)
take the derivate, and f '(x)=0
since f '(x)=0 that means f(x) is a constant for all value of x, plug in any number for f(x) and it =0.

Oh schnapples, that is GENIUS!

Okay not exactly, but not something you'd think up all the time.
