Quadratic Equation Solver

(Originally posted on Zuneboards)

This is the first app that i made. It solves quadratic equations using the quadratic formula. To use it, just enter the values for a, b, and c, and press enter. It can give both real and complex solutions,  but it may not reduce fractions in complex answers. For example: if you enter 1 for a, 4 for b and 5 for c, it will give the solutions (-4-2i)/2 and (-4+2i)/2, but it can be reduced to -2-i and -2+i.  (Update: It will now reduce fractions.)

Update: version 1.01 – fixed a bug that made it so a decimal point cannot be entered after entering another number with a decimal point. (2/6/10)

Update: version 1.02 – prevents user from entering only “.”, “-”, and “-.”. It will also now reduce fractions. (2/7/10)

Update: version 1.03 – fixed a rounding problem and made it so that a complex solution will always include a single + or – instead of +- or –. (2/11/10)

Number Guess

(Originally posted on Zuneboards)

This is a simple number guessing game. It picks a random number between 20 and 2500 and then picks a number between 1 and that number. It will ask you to guess the number, and it will tell you if it is higher or lower than your guess. A point is added to your score after every guess, so lower scores are better than higher scores.

Now this app has new graphics thanks to stampede247 on zuneboards.

Metronome

This is a simple metronome app. The tempo is can be adjusted by sliding your finger up or down on the slider, or by pressing the “+” or “-” buttons. It also has a tuner that can play all notes in an octave and a “tempo finder” where the program calculates the tempo of the beat you tap out based on your last 6 taps.
