1. What is Right Triangle Trigonometry?

Right triangle trigonometry deals with the relationships between the angles and sides of right triangles. The primary trigonometric functions are sine (sin), cosine (cos), and tangent (tan), each representing a ratio of two sides.

2. How Does the Calculator Work?

The calculator uses the sine function formula:

Where:

• \( θ \) — Angle in degrees (between 0° and 90°)
• \( opp \) — Length of the side opposite to angle θ (meters)
• \( hyp \) — Length of the hypotenuse (meters)

Explanation: The calculator can find any missing value when given two of the three variables (angle, opposite side, hypotenuse).

3. Applications of Right Triangle Trigonometry

Details: Used in architecture, engineering, physics, navigation, and many other fields where angle and distance measurements are important.

4. Using the Calculator

Tips: Enter any two known values (angle + opposite side, angle + hypotenuse, or opposite side + hypotenuse) and the calculator will compute the missing value.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of valid angles?
A: Angles must be between 0° and 90° (exclusive) for a right triangle.

Q2: What units should I use?
A: The calculator uses meters, but any consistent unit can be used as long as all lengths are in the same unit.

Q3: Can I calculate cosine or tangent with this?
A: This calculator specifically calculates sine relationships. For cosine or tangent, different ratios would be needed.

Q4: What if I get an error?
A: Make sure you've entered valid numbers (positive values, angle between 0-90°) and that you're not dividing by zero.

Q5: How accurate are the results?
A: Results are accurate to floating-point precision, displayed with 2 decimal places for clarity.
