Find the Values of Theta in Degrees and Radians in the First Quadrant

The video tutorial explains how to determine the angle Theta when the sine of the angle equals 1/2. It begins by clarifying that sine represents the Y coordinate on the unit circle. The instructor then identifies that the problem is limited to angles between 0 and 90 degrees or 0 and π/2 radians. By examining the unit circle, the instructor finds that the Y coordinate equals 1/2 at 30 degrees. Thus, the solution to the problem is Theta equals 30 degrees.
