Problems with Solutions on Trigonometric Ratios

Solutions of Trigonometric Ratios (1) If sin A = 4/5, find the other trigonometric ratios of the angle A. Solution: Let us draw a right △ ABC in which ∠B = 900 We know that,   sin A = 4/5 = BC/AC Therefore, if BC =4k, then AC = 5k, where k is a positive number. Now, using […]

Six Trigonometric ratios in right triangles

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 […]
