I have to make a video explaining this problem, sent by the person who hired me, but it doesn't appear to be correct.
What is the value of cos( + 301/2)?
This is the solution given:
cos(+301/2) = cos(+75*2+ /2)= cos(+ /2)
When I use degrees = radians * 180/pi, that answer isn't correct. And when I plug in the original cos (pi+301pi/2) into google calculator, it isn't 0.
Am I missing something?
