## Description

Taking precalculus? Then you need the Wolfram Precalculus Course Assistant. This definitive app for precalculus—from the world leader in math software—will help you work through your homework problems, ace your tests, and learn calculus concepts. Forget canned examples! The Wolfram Precalculus Course Assistant solves your specific precalculus problems on the fly, including solving equations, vector arithmetic, statistics, and much more.

This app covers the following topics applicable to precalculus and trigonometry:

- Evaluate any numeric expression or substitute a value for a variable
- Solve a single equation or a system of equations
- Plot functions on the x-y plane or draw a parametric or polar plot
- Determine the sine, cosine, and tangent of a specific angle in a right triangle
- Simplify, expand, or factor trigonometric functions
- Find the partial fraction decomposition of an expression
- Calculate the dot product, cross product, and magnitude of two vectors
- Identify the mean, median, mode, and standard deviation of a set of data
- Calculate permutations and combinations

The Wolfram Precalculus Course Assistant is powered by the Wolfram|Alpha computational knowledge engine and is created by Wolfram Research, makers of Mathematica—the world's leading software system for mathematical research and education.

The Wolfram Precalculus Course Assistant draws on the computational power of Wolfram|Alpha's supercomputers over a 3G, 4G, or Wi-Fi connection.

## Ratings and Reviews

### Precalculus is *STILL* the Most Important Math Course

#### Oct 24, 2011

The only way to succeed in a math career is to excel in precalc ... And this app will help as a tool for review to make sure you have it right ... if you work hard, this app, as well as the algebra app and the WolframAlpha app will help propel you into calculus with a good math background ... otherwise, change your major to Shakespeare :) If you do continue in math and want to polish a few of the rough edges, a few hours spent within Wolfram MathWorld will be very productive, not to mention that it may be addictive.

### It's more of an answer key

It might be my fault. But I expected this app to be more of "how to do the problem" app but i found it to be just a little behind an answer key. The app needs more development. The only difference between this app and WolframAlpha app is that this one gives like a step (without explanations) to the solution and the rest of the steps are left to your imagination. I would rather buy the solutions manual or just go through the course without this app. This app has not not helped me with precalculus in the very least.

### Wow did I get ripped off

Wolfram alpha is a good web site and calculation engine. And the iPad version is worthwhile, if just barely, because you get a little better iOS interface and keyboard. But after that, nothing. I saw nothing related to pre-calculus, no reference material, no worked problems, no templates. this little app adds no value at all to me, and only 1.99 to W-A. I am embarrassed for their sake.
