For any triangle , we have following formula involving trigonometric ratios. Trigonometry formula for triangle Formula 1 $\frac {sin A}{a} = \frac {sin B}{c} = \frac {sin C}{c}$ Formula 2 $cos A = \frac {b^2 + c^2 -a^2}{2bc}$ $cos B = \frac {a^2 + c^2 -b^2}{2ac}$ $cos C = \frac {a^2 + b^2 -c^2}{2ab}$ Formula […]

In mathematics, trigonometry is a crucial topic that is studied by students in various grades. Trigonometric ratios are ratios of the sides of a right triangle to its angles, and they are used to solve problems related to angles, distances, and heights. In this article, we will discuss the reciprocal of cosine or secant, which

In this post ,we will see how we can write all the Trigonometric ratios of angle A in the terms of sec A. Here we would be focusing on acute angle A only Value of Cos A in terms of sec A $cos A = \frac {1}{sec A}$ Value of Sin A in terms of

Introduction to Pythagorean Triples How to generate Pythagorean Triples There are several methods to generate Pythagorean triples, but one of the most common ways is by using Euclid’s formula a = m² – n² b = 2mn c = m² + n² Where: Proof of Euclid Formula $a^2 + b^2 = (m^2 -n^2)^2 + 4m^2n^2
