Free Graphing Calculator
Free Graphing Calculator by William Jockush is far more than a simple calculator. This free tool can be used as a very resourceful tool in algebra! It can be used to solve almost any equation or triangle and even graph functions!
Free Graphing Calculator has a clear-cut layout, which is ideal for this type of an app. It only has five tabs, all listed at the very bottom of the screen: calculator, equations, graph, reference and more. The first three are self-explanatory. The last two have more details. The reference-tab offers many references not only applicable to algebra, but also to calculus, mechanics, fractions, geometry, language, logic, trigonometry, vectors and many more! The more-tab is where you’ll find your settings, information about the full version, a place to make an in-app purchase of $0.99 to eliminate ads, as well as table, polynomial and triangle solvers!
Because Free Graphing Calculator is all about numbers and being precise, its ads do bother me. However, they only cost a buck to remove permanently, and this app is worth way more than a buck! If you need a little help with your algebra, this graphing calculator could make your grade! It’s that good! It offers more than features than the paid calculator apps, and it’s FREE!
iTunes list Free Graphing Calculator’s features as such:
- Scientific Calculator: Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:
• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.
- Graphing Capabilities:
• Graph up to four equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
- 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!
- 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!
- 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.
- Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition.
- 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.
