If 3 tan a 4 then find sin a and cos a
WebGoogle Classroom. Learn how to find the sine, cosine, and tangent of angles in right triangles. The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: Web7 apr. 2024 · Hint: In the question, it is asked that we have to write $3\tan A=4\sin A$ in terms of cot A and cosec A.
