Question

Find sin theta if cot theta = -2 and cos theta < 0.

Answer 1

I got 1.11 but the closest answer choice is sqrt5/2...

Answer 2

it is not right

Answer 3

sin theta varies from -1 to 1

Answer 4

I got .447

Answer 5

Oh, I see. Thank you for taking the time to visit my question again.

Answer 6

just to check your answer, you say sin theta = 1.11 so sin inv of 1.11 should give you theta right? it gives me invalid input if I put in the calculator.

Answer 7

is .447 one of the choices?

Answer 8

Yup, you're right, because .447 would be the same as sqrt5/5 which matches one of my answer choices
