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!
* 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)
When calling each equation, a screen will show each of the variables used, and if necessary, what units you will need to use. While SI (meters, kilograms, seconds) units are used, some equations call for the temperature to be in Celsius, while others require the temperature to be in Kelvin.
You can download the hpprgm file and the PDF document here:
The PDF document will list the equations available and the variables used. For eqlib, the global variables A-Z and theta are used. The program is free.
P.S. This is not an April's Fool joke, just in case you were wondering.
