cos(-5pi/4) - cos(3pi/4) find the exact value - YouTube
WebApr 23, 2015 · When you take the corresponding angle in the 2nd quadrant, you have 3pi/4, which also gets you sqrt (2)/2. Now the final step: flip the angle across the 2nd quadrant into the 3rd quadrant – you get 5pi/4 ! But since we are in the 3rd quadrant, now, sin is negative. THEREFORE, sin (5pi/4)=-sqrt (2).
