Question 886384: find all solutions for the equation in the interval {0,2pi) cos(theta/2)}} = 0 Found 2 solutions by stanbon, Edwin McCravy:Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! find all solutions for the equation in the interval {0,2pi)
cos theta/2 = 0
----
cosine is zero when the angle is pi/2 or (3/2)pi
---
Solve:
t/2 = pi/2 when t = pi
---
t/2 = (3/2)pi when t = 3pi (This answer is not in the interval (0,2pi).
