Question

How do I determine sin theta to 3 decimal places when tan=1/2 and theta is in the first quadrant?

Answer 1

Can you not provide the solution? just method to getting it?

Answer 2

Thank you:)

Answer 3

tan A = p/b
p = 1, b = 2

sin A = p / (p^2+b^2)^(1/2)

Answer 4

1/sqrt(5)

Answer 5

How would I go about solving this qustion?

Answer 6

Hint

\[\tan \theta = \frac{opp}{adj}\]

Answer 7

How can I solve this?

Answer 8

1/cotA = tan A = p/b

find p and b from sinA

read theta for A
