Lacking the simple stuff to be a Great! I seriously wanted to return the 3 apps i just brought for a refund. I kept them because i have faith that the Wolfram Alpha team will come up with explanations on concepts and examples. Maybe a fee flash cards to make sure us students remwber the formulas. Then I'll pay $20 for an app. Just please don't dissapoint me. Hope to see updates soon. This will make these apps a raging success and lots of money to you guys.

## Pre-Calculus Guide

Calculus may not seem very important to you but the lessons and skills you learn will be with for your whole lifetime!

Calculus is the mathematical study of continuous change. It helps you practice and develop your logic/reasoning skills. It throws challenging problems your way which make you think. Although you may never use calculus ever again after school or college, you will definitely hold on to the lessons that calculus teaches you.

Things like time management, how to be organized, how to accomplish things on time, how to perform under pressure, how to be responsible are just some of the things Calculus helps you become proficient in. Traits that will help you succeed.

Calculus plays a big role in most universities today as students in the fields of economics, science, business, engineering, computer science, and so on are all required to take Calculus as prerequisites.

## Integral Calculator

Hi Guys,

Enter any integral function and this will calculate the answer. It does just what it says on the tin. So if you have integration work that you need to double check, then look no further.

The tool is taken from the selection of tools that appears on my live worksheet app that appears on my wolfram alpha developer page.

Hope it proves helpful.

Cheers,

Mark

## Mathematics

This app will provide you a great tool if you want to plot a mathematic function.

You only have to write formula, and curve will be displayed in a customizable chart.

You can choose minimal and maximal abscissa (by default it is set from -5 to 5).

It is possible to display derivative function, so you can see both f(x) and f'(x) curves.

If you click on "VALUES" button, il shows all values between selected bounds.

You have a trace function that let you move a current point on curve, while its cordinates are displayed.

Likewise, tangent can be displayed on current point.

It can replace your scientific calculator !

Enjoy !

Examples of possible functions :

f(x) = 5x+3

f(x) = 3x^2 (equivalent to 3x²)

f(x) = 4cos(π-x)

f(x) = tan(cos(x))

f(x) = ln(x+10)

f(x) = exp(-3x) (exp is exponential function)

f(x) = xsin(x) - 6/x

## Laplace Transforms Calculator

Hi Guys,

Enter a function and this evaluates the Laplace Transform or the Inverse Laplace Transform. It basically does just what it says on the tin. So if you have Laplace Transform questions that you need to work on, then look no further.

The widget tool is taken from the selection of tools that appears on my wolfram alpha developer page.

Hope it proves helpful.

Cheers,
