Trigonometric Ratios: A Detailed Explanation Trigonometric ratios are the ratios of the lengths of sides in a right-angled triangle. These ratios are fundamental in trigonometry and are used to relate the angles of a triangle to the lengths of its sides. There are six primary trigonometric ratios. sine, cosine, tangent, cosecant, secant, and cotangent. Here’s […]

Read More →Trigonometric ratios in right triangles In a triangle, if any one angle is a right angle ( that is a 90 degree angle) then the triangle is called right triangle. A triangle has three sides, the longest side of the triangle is opposite of right angle called Hypotenuse, and the other two sides including the right […]
