Pi / 5 would be in Quadrant I.
7*pi/5 = 1.4*pi pi < 1.4*pi < 1.5*pi and so the angle is in the third quadrant.
first
The angle ( \frac{5\pi}{4} ) radians corresponds to 225 degrees, which is located in the third quadrant of the unit circle. In this quadrant, the sine function is negative. The reference angle is ( \frac{\pi}{4} ), for which the sine value is ( \frac{\sqrt{2}}{2} ). Therefore, ( \sin\left(\frac{5\pi}{4}\right) = -\frac{\sqrt{2}}{2} ).
