Derivative and first order partial derivative : diff derive deriver

diff (or derive) takes two arguments : an expression and a variable (resp a vector of the variable name) (see several variable functions in 1.50). If only one argument is provided, the derivative is taken with respect to x
diff (or derive) returns the derivative (resp a vector of derivative) of the expression with respect to the variable (resp with respect to each variable) given as second argument.
