Introduction Imagine this: two students with equal aptitude and school support, but one ends the year scoring 95%+ while the other lingers at 80-85%. What made the difference? Often it’s not just hard work — it’s how you work, and with whom. The top scorers (toppers) routinely supplement their school learning with targeted, smart online coaching. In this post, we…

Proof of 3 Important Trigonometric Identities (Class 10 Maths)
Introduction Trigonometric identities often confuse Class 10 students, but they are actually the simplest once you know the logic. These identities are the backbone of trigonometry and are repeatedly used in exams. In this blog, I’ll walk you through the proof of three trigonometric identities with clear steps and examples. You’ll also find a video lesson embedded for easier understanding.…
Example 7: In a ΔPQR, right-angled at Q (see Fig. 8.20), PQ = 3 cm and PR = 6 cm. Determine ∠QPR and ∠PRQ.
Given: PQ = 3 cm, PR = 6 cm, ∠Q = 90° To find: ∠QPR = ? and ∠PRQ = ? Solution: In right ΔPQR, Let ∠PRQ = θ Also, (p / h) = sin θ PQ / PR = sin θ 3 / 6 = sin θ 1/2 = sin θ We know, sin 30° = 1/2 So, θ…

Example 2: If ∠B and ∠Q are acute angles such that sin B = sin Q, then prove that ∠B = ∠Q
To Prove: ∠B=∠Q\angle B = \angle Q Given: ∠B and ∠Q are acute angles sin B = sin Q Proof: Let us consider two right triangles: ΔABC, right-angled at C ΔPQR, right-angled at R Step 1: Write sine values in each triangle In ΔABC: sinB=ACAB⋯(1)\sin B = \frac{AC}{AB} \quad \cdots (1) In ΔPQR: sinQ=PRPQ⋯(2)\sin Q = \frac{PR}{PQ} \quad \cdots…
Example 1 : If tan A = 4/3, find other Trigonometric Ratios of angle A
This is a typical Class 10 CBSE trigonometry problem. If you’re given tan A = 4/3, the goal is to find the remaining five trigonometric ratios. Let’s solve this step by step using the triangle sides: perpendicular, base, and hypotenuse. Step-by-Step Solution: We are given: tan A = 4/3 That means: Perpendicular = 4 units Base = 3 units Now,…

Why Sin A and Cos A are always less than 1 in Right Triangles – Class 10
Let’s break this down step by step so you fully understand why this is always true. 📌 What Is a Right Triangle? A right triangle is a triangle with one 90-degree angle. The side opposite this right angle is called the hypotenuse. The other two sides are called the perpendicular and the base — they are always shorter than the…
