I can't work out how to do 2 bread and butter things:

1. get an answer in exact form, ie: $$\frac{\pi}{2}+\frac{\pi}{2}=\pi$$ and,

2. how to differentiate $$x^2\ or\ 2x^3+3x$$ without having to stipulate a value for $x$; ie: simply to get the first derivative of an f(x); conversely, how to do this for integration without stipulating a domain, in other words, how to calculate an indefinite integral

(I've read, and am reading again, the appropriate parts of the manual, honest!)

Thanks,

(Perhaps this should go in Calculus, huh?)
