ASCII math notation
A notation widely used on Internet sites, where typing complicated mathematical symbols is rather cumbersome.
Long-hand:
- e f(x,y,...)
Short-hand:
exp(f(x,y,...))
Long-hand:
- limr→c(f(r,x,...))
Short-hand:
lim(f(r,x,...),r,c)
where c can be a finite quantity, or ∞. The limit from the left is called llim, and the limit from the right rlim.
Long-hand:
- ∑r=ab f(x,r,...)
- ∑r=a to b f(x,r,...)
Short-hand:
sum(f(x,r,...),r,a,b)
Long-hand:
- The Taylor series of degree k for f(x,y,...) with respect to x about a.
Short-hand:
tayl(f(x,y,...),x,k,a)
Long-hand:
- The Maclaurin series of degree k for f(x,y,...) with respect to x.
Short-hand:
macl(f(x,y,...),x,k)
Long-hand:
- ∫ab f(x) dx
Short-hand:
int(f(x),x,a,b)
Long-hand:
- d(f(x))/dx
Short-hand:
d/dx(f(x))
