This is a multi-function calculator made by a middle school student. Pythagorean theorem: Calculate value for c based on user inputs. Factoring: Plug in values for a b and c, the computer will automatically calculate two zeros. The log will display the calculation process. Trigonometric basic: Input minimum of two values and choose calculation target(angle x or y). The computer will automatically choose sine, cosine or tangent and calculate the angle measurement in degrees. Log will display the calculation process including the radian measurement for the angle. Attention: *This only works with a right triangle* Trigonometry advanced. Input all three side measurement. The computer will use the law of cosine and sine to calculate the angle measurement for all three angles. Log will display the calculation process including the radian measurements. Attention: *Three side measurement are required* For more information including how to do all of the math behind the scene please visit www.nspiresoftware.net.
