Differential Calculus

Besides the examples on this page, please see the discussion in ["BasicCalculus"].

Functions

Piecewise fcns, polynomials, exponential, logs, trig and hyperboic trig functions.

SAGE can compute \lim_{x\rightarrow 0}\frac{\sin(x)}{x}:

sage: limit(sin(x)/x,x=0)
1

SAGE can differentiate x^2\log(x+a) and \tan^{-1}(x)=\arctan(x):

sage: diff(x^2 * log(x+a), x)
2*x*log(x + a) + x^2/(x + a)
sage: derivative(atan(x), x)
1/(x^2 + 1)

...

(Some schools teach this topic as part of integral calculus.)
