Simplify sin(4)

Problem

sin(4)

Solution

1. Identify the expression as the sine of the number 4.

2. Determine the units, which are assumed to be radians since no degree symbol is present.

3. Evaluate the expression. Since 4 is not a standard angle (like π π/2 etc.), the expression sin(4) is already in its simplest exact form.

4. Approximate the value if a decimal is required. Since π<4<(3*π)/2 the angle is in the third quadrant, meaning the result is negative.

Final Answer

sin(4)=sin(4)
