Evaluate sin(45 degrees )

Problem

sin(45)

Solution

1. Identify the angle in the context of the unit circle or a special right triangle.

2. Recall that for an angle of 45 the coordinates on the unit circle are (√(,2)/2,√(,2)/2)

3. Apply the definition of the sine function, which corresponds to the ycoordinate of the point on the unit circle.

4. Determine the value based on the ycoordinate.

Final Answer

sin(45)=√(,2)/2
