diff

Differentiate

Syntax

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

Description

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

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.

Examples

Assume

• syms x t
  

Then

• diff(sin(x^2))
  

returns

• 2*cos(x^2)*x
  

and

• diff(t^6,6)
  

returns

• 720
