Evaluate -(3pi)/4

Problem

−(3*π)/4

Solution

1. Identify the expression as a negative angle measured in radians.

2. Determine the position of the angle on the unit circle by rotating clockwise from the positive x-axis.

3. Calculate the equivalent positive coterminal angle by adding 2*π to the given value.

−(3*π)/4+(8*π)/4=(5*π)/4

4. Convert the radian measure to degrees if necessary to visualize the angle.

−(3*π)/4⋅180/π=−135

Final Answer

−(3*π)/4=−135
