Introduction

The Math Handbook Calculator has the function of machine learning. It is unique in the world to solve the function of any order (such as 0.5 order) differential equations. Enter mathematical formulas on the Mathematics Handbook website, click continuously to calculate calculus, solve equations, give analytical solutions and numerical solutions and diagrams, interactively zoom in the drawing, and zoom in with the mouse wheel. You can use it on your mobile phone to learn computing and development anytime, anywhere.

Getting Help

It has extensive built-in documentation, accessible by typing a math function or a function name or a keyword, followed by a question mark? e.g.
  • or click the button. e.g.

  • or

  • to matrix calculator

    Rules

    It uses := for assignment. It uses = for equation in MathHandbook and for assigment in JavaScript. It uses ==, <=, >=, < and >, for comparison, != in JavaScript and <> in MathHandbook.

    put function arguments in parentheses: sin(x) -- correct, sin x -- incorrect; do not omit multiplication: x*sin(x) -- correct, x sin(x) -- incorrect. Usual keywords are lowercase, which are different from uppercase, e.g. sin is different from Sin. Its default variable is small letter x, but its default index variable in discrete math is k.

    By default, the unknown function is y(x) and its initial value is y(0)=0.
    For ordinary differential equation, an independent variable is x.
    For a partial differential equation, the unknown function is y(1,x) and y(1,t) with its two independent variables x and t.
    For a system of equations, two unknown functions are x(t) and y(t) with an independent variable t.

    There are 6 way to input derivative of y: y(1,x), ds(y,x), d(y(x),x), ds(y), d(y(x)), y'
    There are 3 way to input second order derivative of y: y(2,x), ds(y,x,2), d(y(x),x,2)
    There are 3 way to input the 0.5 order derivativeof y: y(0.5,x), ds(y,x,0.5), d(y(x),x,0.5)
    There are 4 way to input the 0.5 order integral of y: y(-0.5,x), ds(y,x,-0.5), d(y(x),x,-0.5), ints(y,x,0.5)

    more are in Differential equation and example.

    Computing

  • by calculator
  • Cloud computing 云计算 = Web Address calculator 网址计算器 = Web calculator = URL calculator
    Input your formula x from URL in browser to compute x, and share your computation with URL. please replace the plus sign + with %2b, the power sign ^ with **, as URL did not know + ^.

    MathHandbook

    - online Computer Algebra System for symbolic computation of any order of fractional derivative. It has three versions:
    1. Java version: Java Applet run on phone and tablet and computer that support Java online and off-line. iPhone and iPad do not support Java so it cannot run. Do you want to run MathHandbook offline? please order java version.
    2. Phone version: run on any phone online.
    3. DOS version: run on PC. Its old name is SymbMath.
