sin[cot^-1 (4/3)+sin^-1 (-5/13)]

Evaluate using Principal Values. Please show *all* work so I know what I'm doing. Thank You.

Answers in fraction form would be great, thank you! (That's what we use.)

sin[cot-1(4/3) + sin-1(-5/13)] given


a) find the angles

cot-1 (4/3) = 1 / tan-1 (4/3) = 1 / 0.9273 = 1.0784 cotangent = 1/tangent

sin-1 (-5/13) = -0.3948


b) add the angles

sin[1.0784 + (-0.3948)] = sin[0.6836]


c) evaluate

sin[0.6836] = 0.6316

You will need to use radians as a multiple of pi
