Limits
Long-hand:
Short-hand:
where c can be a finite quantity, or ∞. The limit from the left is called llim, and the limit from the right rlim.
Most commonly:
- lim_r->c f(r,x,...)
Sums
Long-hand:
- sum(f(x,r,...),r,a,b)
Taylor/Maclaurin series
Long-hand:
- The Taylor series of degree k for f(x,y,...) with respect to x about a.
- tayl(f(x,y,...),x,k,a)
- The Maclaurin series of degree k for f(x,y,...) with respect to x.
- macl(f(x,y,...),x,k)
Integrals
Long-hand:
- int(f(x),x,a,b)
Derivatives
Long-hand:
- d/dx(f(x))
