Trigonometry Practice & Questions
Trigonometry assesses right-triangle ratios, fundamental Pythagorean identities, and radian/degree angle calculations.
Core Concepts in Trigonometry
Questions from this topic consistently evaluate the following core principles across SSC, Railways, and Banking papers:
- Fundamental identities (sin²θ + cos²θ = 1, sec²θ - tan²θ = 1)
- Complementary angles (sin(90-θ) = cosθ)
- Max/Min values of a sinθ + b cosθ
- Value substitution method (putting θ = 0°, 45°, 90°)
Exam Speed Strategy & Shortcuts
- Check whether substituting θ = 45° or 30° simplifies identity proofs without making denominators zero.
- Max value of a sinθ + b cosθ is √(a² + b²).
