App Description

Understanding right triangle trigonometry can be complicated but this program simplifies understanding. Both from an educational standpoint where the student needs to understand the relationships between the sides of a right triangle and an engineering standpoint where the user needs evaluate the dimensions of a triangular bracket this user friendly program is for you. Both a help screen and glossary of terms screen have been included to simplify understanding. The “Solve For:” button allows the problem to be setup using sine, cosine tangent or angle functions. Using the adjustor controls or keyboard the sides of the triangle and angle are calculated and displayed. A display shows the actual shape of the triangle as the user adjusts or sets the side or angle values. Help and glossary screens with a full set of equations are provided to further help in understanding right triangle trigonometry. When you are done simply Email the results to your home computer for further analysis. This program is a must for Students and Engineers. It makes the complex understandable. Simply the best trigonometry program.

- Updates as You Edit
- Displays actual shape of the triangle
- Number Pad Digital Entry
- Adjustor buttons to increment the inputs
- Help Screen, Glossary
- Email results to your computer

Example: A simple triangle with side a = 1 and c = 2. The result is an angle of 30 degrees with b = 1.732. The sin function is selected showing the equations the appropriate function and an equation for b. Try solving for other functions such as cos and tan.

Change any of the parameters by the keyboard or by using the adjuster arrow buttons.

Note that as the user changes any entry the calculations change as well and the triangle in the display. The limits of calculations are zero degrees and 90 degree angles. The program warns for zero entries. The user can work directly in inches or millimeters so that real world problems can be calculated.

Look for other Ray Tools app’s including Ohms Law , linear, quadratic, Polynomial, exponential and logarithmic equations.
