# Wolfram launches seven course assistant apps on Windows Phone to turn you into a math whiz After officially launching WolframAlpha for Windows Phone and Windows 8.1 earlier this year, Wolfram is now providing seven new course assistant apps. The apps -- which are powered by the WolframAlpha computational knowledge engine -- are designed to assist you in solving math problems and learning new concepts with ease.

## Algebra Course Assistant

First up is the Algebra Course Assistant, which covers topics found in Algebra I, Algebra II, and College Algebra:

• Evaluate any numeric expression or substitute a value for a variable.
• Simplify fractions, square roots, or any other expression.
• Solve a simple equation or a system of equations for specific variables.
• Plot basic, parametric, or polar plots of the function(s) of your choice.
• Expand any polynomial.
• Factor numeric expressions, polynomials, and symbolic expressions.
• Divide any two expressions.
• Find the partial fraction decomposition of rational expressions.

As with all Wolfram apps, Algebra Course Assistant is universal (buy it once and use on both Windows and Windows Phone), and is available now for \$1.99.

## Calculus Course Assistant

For students taking calculus courses, the Calculus Course Assistant is bound to come in handy. The \$2.99 app aims to teach you concepts from Calculus, AP Calculus AB, AP Calculus BC, Calculus I, and Calculus II:

• Evaluate any numeric expression or substitute a value for a variable.
• Plot basic, parametric, or polar plots of the function(s) of your choice.
• Determine the limit of a function as it approaches a specific value.
• Differentiate any function or implicit function.
• Find the critical points and inflection points of a function.
• Identify the local and absolute extrema of a function.
• Integrate a function, with or without limits.
• Sum a function given a lower and upper bound.
• Find the closed form of a sequence or generate terms for a specific sequence.
