COMPLETE<br> Find the value of the function for O.<br> sin(45°) = ?
geniusboy [140]

Answer:  \sqrt{2}/2 which is Choice B

This is the same as writing \frac{\sqrt{2}}{2}

The second "2" is not under or inside the square root.

==========================================================

Explanation:

Refer to the unit circle below. I've highlighted the angle 45 degrees and its corresponding sine value. It's the y coordinate of the point on the unit circle, for this particular angle.

Therefore, \sin(45^{\circ}) = \frac{\sqrt{2}}{2}

--------------

You could alternatively draw out a 45-45-90 triangle. Let x be the leg length and the hypotenuse is 1 unit long. Solve x^2+x^2 = 1 for x and you should get x = \frac{\sqrt{2}}{2} as the length of each leg.

Then take the ratio of the opposite over hypotenuse to find the same answer mentioned above.
