Trigonometry is the study of the relationship between the sides and angles of a triangle.
Two angles are said to be complementary of their sum is equal to 90° .
θ & (90° - θ) are complementary angles.
An equation involving trigonometry ratios of an angle is called is called a trigonometric identity, if it is true for all values of the angles involved. For any acute angle θ, we have 3 identities.
i) sin² θ + cos² θ = 1 ,ii) 1 + tan² θ = sec² θ , iii) cot² θ +1 = cosec² θ.
