Question

sin ( cot

Answer 1

what is your question?

Answer 2

find sin tan^-1 (-1/2)?

Answer 3

sin ( arc tan (-1/2)) = ?

Answer 4

sorry no

Answer 5

let tan^(-1)(-1/2)=A then tanA=-1/2 this gives sinA/cosA=-1/2,
sinA/sqrt(1-sin^2(A))=-1/2 (since cos^2(A)+sin^2(A)=1),this gives us
sinA=+-1/sqrt(5), the question sin(tan^(-1)(-1/2))=sinA=+-1/sqrt(5).
