diff - Differentiate symbolic expression

Syntax

diff(S) diff(S,'v') diff(S,n) diff(S,'v',n)

diff(S) differentiates a symbolic expression S with respect to its free variable as determined by symvar.

diff(S,'v') or diff(S,sym('v')) differentiates S with respect to v.

diff(S,n), for a positive integer n, differentiates S n times.

diff(S,'v',n) and diff(S,n,'v') are also acceptable.

Assume

syms x t

Then

diff(sin(x^2))

returns

2*x*cos(x^2)

and

diff(t^6,6)

returns
