Question
The value of tan is
The correct answer is:
for given expression tan we need to convert sin-1 into tan-1
sin-1(3/5) = tan-1(3/4)
tan[sin-1(3/5)+tan-1(2/3c)] = tan[tan-1(3/4)+tan-1(2/3)]
tan-1(x) + tan-1(y) = tan-1[(x + y) / (1-xy)]
tan[tan-1(3/4)+tan-1(2/3)]=tan[tan-1((3/4+2/3) / (1-3/4*2/3))]
=tan[tan-1(17/6)]
=17/6
ans is 17/6
tan-1(x) + tan-1(y) =tan-1 [(x + y) / (1-xy)] (1 > x y)
tan[tan-1(x)] = x
