The program eqnlib offers 47 equations for HP Prime’s Solver App. Just run the eqlib program, select the

category that you are interested in, and select the equation within that category and you are off and running!

Categories include:
* Geometry (areas, volumes, surface areas)
* Finance (monthly loans, sales tax, break-even)
* Temperature Conversion (Fahrenheit to and from Celsius)
* Physics: Problems of Motion (linear distance, circular motion, pendulums, terminal & escape velocity)
* Sound (speed of sound, Doppler effect, loudness)
* Optics (Lens and Snell equations, spherical refraction)
* Electronics (2 resistors series and parallel, thermal noise, Ohm's Law)
* Astronomy (parallax, luminosity, Kepler's 3rd Law, time dilation)
* Great Circle Calculations
* Angle of Incidence Calculations
* Gases (Ideal and Boyle's Gas Laws, heat capacity, air density, isothermal expansion)
* Fluids (depth pressure, fluid flow, Bernoulli's Equation)

This is great work, EdPi314; I can't believe I missed this topic for over a month. Out of curiosity, was it any particular need that inspired you to create this, or did you just feel like a general solver program would be a boon to math and science students (and engineers) using the Prime? Finally, may I ask that you please upload this program to the HP Prime Science Programs folder in the Cemetech Archives when you get a chance?

Thank you, and the program has been uploaded under the HP Prime Math Programs section.
