A powerful, flexible graphing calculator . . . and it’s free!
Does way more than most of the paid calculators out there . . . let alone the free ones.
2. Graphing. Capabilities:
3. A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!
4. Constants for scientific calculations — speed of light, strength of gravity at Earth’s surface, etc. etc. etc. Tapping on a constant will insert it into your calculation — i.e, you don’t have to key in the value. Again, great for doing physics homework!
5. It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6. Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.
Compatibility: iPhone and iPod touch. Requires iOS 4.0 or later.
