Trigonomics combines essential tools for calculating triangles, exploring the unit circle and waves, looking up identities, and graphing with custom functions.

1. Triangle Solver - Provide the minimum combination of triangle side lengths and angles and Trigonomics draws the resulting triangle.

• Calculates the area and perimeter
• Alerts you when entered values cannot create a triangle
• Detects ambiguous case when entered values can create two different triangles
• Change a single value or multiple values at a time
• Rotate the triangle

2. Explorers

• Unit Circle - Understand the key relationships between an angle and its trig functions!
• Wave - See what happens to a wave when you adjust the amplitude, frequency, and phase.
• Right Triangle - Focus on a right triangle and all of its trig results.

3. Identities - Look up the most common (and some not-so-common) trig identities.

4. Graph - Plot up to three trigonometric functions at the same time.

• Enter your own custom functions!
• Draw once or loop the graph continuously
• Tap and hold on the graph to bring up a magnifying glass for precision
• See the unit circle being drawn as functions are plotted

Nice to reference unit circle

Im a student of ee and use it for referencing phase angles. It's useful to put your finger on the unit circle and see the outputs. I highly recommend the app for students!

Like the previous user stated this app is for educational purposes. I agree. As a student the explorers are very good to use when learning how to graph sinusoids w/ phase angles by hand (sig&systems).

A very nice feature is the function grapher. Easy inputs and UI makes this section nice to work with. I had a question about sinθcosθ and its amplitude. The function grapher plots the function and there's a table underneath to look up values. I highly recommend this feature!

I have had good interactions with the dev. I had purchased the base station app for my intro to dig systems class and notice the background made the numbers unreadable. After sending in a notice email, I received a prompt reply thanking me for the input and asking for more details. Within a few weeks a new update solved the problem. They are very eager to hear and implement input from black box sources! I really commend them for there programs.
