LIBRARY

newton.simplify

Simplify the given expression

newton.simplify('x + x + 2 * 8')
returns
2x + 16

Argument(s): a string of the expression that is to be simplified

Return: A string of the simplified expression

newton.factor

Factor the given expression

newton.factor('x^2 - 1')
returns
(x - 1) (x + 1)

Argument(s): a string of the expression that is to be factored

Return: A string of the factored expression

newton.zeroes

Find the x values at which the function expression is equal to 0

newton.zeroes('x^2 - 1')
returns
[1, -1]

Argument(s): a string representation of the function of which the zeroes are to be found

Return: An array of the zeroes of the function

newton.derive

Find the first derivative of the function expression

newton.derive('x^2')
returns
2 x

Argument(s): a string representation of the function to be differentiated

Return: The first derivative of the given function expression

newton.integrate

Find an integral of the function expression

newton.integrate('x^2')
returns
1/3 x^3

Argument(s): a string representation of the function to be integrated

Return: A string representation of an integral of the given function expression

newton.tangent

Find the tangent line of a function at a given x value

newton.tangent('x^2', 1)
returns
2 x + -1

Argument(s): 1. a string representation of the function on which the tangent is to be found 2. a number representing the x value at which to find the tangent of the function

Return: A string representation of the tangent function expression

newton.areaUnder

Find area under a given function between two x values

newton.areaUnder('x^2', { start: 1, finish: 3})
returns
8

Argument(s): 1. a string representation of the function under which the area is to be found 2. an object with properties start and finish representing the x values between which the area will be found under the function

Return: A number representation of the area under the given function between the two x values
