Question

Please help with pre cal!

Sketch: theta=(5x)/4 in standard position.

A. Determine two coterminal angles (one positive and one negative).

B. Convert the angle to degree measure.

Answer 1

Compare your theta = 5Pi/4 (not 5x/4) to 4Pi/4 = Pi. Note that Pi = 180 degrees. To graph that, you'd start at the positive x-axis and rotate your ray counterclockwise until the tip of your ray points due left. Your ray will be Pi radians from the positive x-axis.

Now note that 5Pi/4 is Pi/4 (or 45 degrees) PAST Pi, still going counterclockwise. That places this angle in Quadrant 3. Can you now graph the angle 5Pi/4? If you need further info / guidance, please say what you need to know next.

Answer 2

@mathmale would it look something like this? I'm not too familiar with this
