graph the polar function r=2cos[tex]\theta[/tex] (-[tex]\pi[/tex]/2 [tex]\leq[/tex] [tex]\theta[/tex] [tex]\leq[/tex] [tex]\pi[/tex]/2) sorry that last theta/2 should be pi/2. new to this math text
The Attempt at a Solution
I graphed the positive part right, I think. it seems to trace a half circle. I get confused when it comes to the negative radians. what would this trace out in full. Excuse me but its been a while since trig.
