Trigo trigonometric ratio of complementary angle

1.	Trigo trigonometric ratio of complementary angle
Answer» Trigonometric Ratios Of Complementary AnglesWe know complementary angles are pair of angles whose sum is 90°Like 40°, 50°, 60°, 30°, 20°, 70°, 15°, 75° ; etc,Formulae:sin (90° – θ) = cos θ, cot (90° – θ) = tanθcos (90° – θ) = sin θ, sec (90° – θ) = cosec θtan (90° – θ) = cot θ, cosec (90° – θ) = sec θ
