Trigonometry Notes for CBSE Class 10 — Free AI Cheatsheet

Trigonometry in Class 10 CBSE is a high-weightage chapter — expect 8-10 marks in board exams including the heights and distances application question. The chapter introduces six trigonometric ratios (sin θ, cos θ, tan θ, cosec θ, sec θ, cot θ) and their relationships in right-angled triangles.

The most important thing to memorize is the standard angle table — values of all six ratios at 0°, 30°, 45°, 60°, and 90°. Our AI cheatsheet presents this table clearly along with a memory trick to derive any value instantly without rote learning. The three fundamental identities (sin²θ + cos²θ = 1, 1 + tan²θ = sec²θ, 1 + cot²θ = cosec²θ) are essential for proving problems.

Heights and Distances is a guaranteed 3-4 mark question in CBSE boards. The cheatsheet covers angle of elevation, angle of depression, and the most common problem types with step-by-step solutions. Practice the 10 MCQs to master the application of trigonometric ratios in real-world scenarios.

Frequently Asked Questions — Trigonometry

What are the trigonometry formulas for Class 10?▼

Key formulas include: sin θ = opposite/hypotenuse, cos θ = adjacent/hypotenuse, tan θ = opposite/adjacent. Important identities: sin²θ + cos²θ = 1, 1 + tan²θ = sec²θ, 1 + cot²θ = cosec²θ. Plus complementary angle relations like sin(90° - θ) = cos θ.

How to memorize trigonometry values for Class 10?▼

Use this trick: write 0, 1, 2, 3, 4 for angles 0°, 30°, 45°, 60°, 90°. Divide each by 4, take the square root — that gives you sin values. For cos, reverse the order. Coachingle's cheatsheet includes this memory trick with a visual table.

How many marks is trigonometry in CBSE Class 10?▼

Trigonometry (including heights and distances) carries 8-10 marks in the CBSE Class 10 board exam. It's one of the highest-weightage topics in Mathematics, making it essential for scoring 90+.
