Problem

3*sin(π/2)

Solution

1. Identify the value of the trigonometric function sin(π/2) using the unit circle.

2. Recall that at the angle π/2 radians (or 90, the ycoordinate on the unit circle is 1

3. Substitute the value 1 into the expression.

sin(π/2)=1

4. Multiply the constant 3 by the result of the trigonometric function.

3⋅1=3

Final Answer

3*sin(π/2)=3
