Tan(A) =1/8 and Csc(A) > 0 Sketch a right triangle with legs of length 1 and 8. The hypotenuse of this right triangle is √(1² + 8²) = √65 Now use the definitions of the other functions So, Sin(A) = 1/√65 Cos(A) = 8/√65 Cot(A) = 8/1 Csc(A) = √65 / 1 Sec(A) = √65 / 8 Please note Csc(A) > 0 as requied!
