Frequently Asked Questions
What are the basic trigonometric functions?
The six trig functions relate angles to side ratios in a right triangle: sin(θ) = opposite/hypotenuse, cos(θ) = adjacent/hypotenuse, tan(θ) = opposite/adjacent. Their reciprocals are csc, sec, and cot respectively.
How do I convert between degrees and radians?
Radians = degrees × π/180. Degrees = radians × 180/π. Key values: 180° = π rad, 90° = π/2 rad, 60° = π/3 rad, 45° = π/4 rad, 30° = π/6 rad.
