Public Functions

def(expr)

• Definition: Domain of expr

• Type: Program

• Output: Stores result in global variable def_val, and full result in global variable def_val_raw

def_info(expr, print)

• Definition: Domain analysis of expr and derivative of expr. Displays info if print is true

• Type: Program

• Output: Stores whether the domains are equal in global variable def_match

def_print(expr)

• Same as def(expr) but prints out def_val and def_val_raw

range(function)

• Range of function

fn_info(function)

• Analysis of function

inverse(function)

• Inverse function of function

rational_fn(num, den)

• Rational function analysis

• (where P is num and Q is den)

crit_points(function)

• Critical points of function

• Displays f'(x) and roots of f'(x)

• Displays 2 domains of f(x) and f'(x)

inflect_points(function)

• Inflection points of function

• Displays f''(x) and roots of f''(x)

• Displays domain of f''(x)

parity(function, out_value)

• Parity of function (even/odd/neither)

• Stores result in variable with name out_value

antiderivative(function, variable)

• Antiderivative of function with respect to variable

syndiv(poly, div)

• Synthetic division of poly by div

• Returns a list of the coefficients with the last element

• the remainder

bernoulli(m)

• Returns Bernoulli number (+) m (for m>0)

bernoulli_n(m)
