Question

prove that sin^-1(3/5)+ cos^-1 (5/√26)= tan^-1(19/17)
plz give Ans step by step explanation​

Answer 1

$\huge\boxed{Answer}$

Sin-¹ (3/5) + Cos-¹(5/√26)

tan-¹(3/4) + tan-¹(1/5)

tan-¹ {(3/4) + (1/5) / (1 - 3/4 * 1/5)}

tan-¹ {(15 + 4)/20 / (1 - 3/20)}

tan-¹ {(19/20) / (17/20)}

tan-¹( 19/20 × 20/17)

tan-¹ (19/17)
