# Math Handbook Calculator

## - Computer Algebra System of Fractional Calculus

First line of buttons are for algebra to return function, second line of button are for calculus to return function, third line of buttions are for discrete math with default index variable k to return value, forth line of buttions are for numeric compution to return number. 5th and 6th line of buttions are to plot2D graph. 7th and 8th lines of buttion are to plot3D graph. The same color buttons are a pair of inverse operators, its result can be checked each other if it returns origial function or not.

## MathHandbook

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.

It has three versions:

- Phone version: run on any phone online. It does not requires to download anything.
- Java version: Java Applet run on any computer that support Java
**online and off-line**. Please contact us if you want it.

- PC version: DOS version run on PC. Its old name is SymbMath, you can download it.

SymbMath - PC DOS version of symbolic computation Computer Algebra System.

## Rules:

put function arguments in parentheses: sin(x) -- correct, sin x -- incorrect; do not omit multiplication: x*sin(x) -- correct, x sin(x) -- incorrect. x**y or pow(x,y) for power. 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.

## How to use?

see help

### Example:

f(x) = x^2; f(2)

d(f(x_), x_) := sin(x);

integrate(f(x_), x_) := cos(x);

**algebra**: convert.

**calculus**: limit, nth derivative, differentiation, integral, fractional calculus, convert to integral.

**equation**: Inequalities, congruence equation, Dorphine equation, modulus equation, recurrence equation, (fractional) differential equation, (fractional) integral equation, by solve(), dsolve(), lasolve(), rsolve().

**discrete math**: sum, partial sum, indefinite sum, infinite sum, convert to sum.

**interactive plot**zoom by mouse wheel: polar plot, parametric plot, implicit plot, tangent plot, secant plot, plot, plot2D, plot3D, parametric3D, parametric3Dxy, implicit3D, complex3D, spin3D

**animation**:
