anonymous · Answer

Okay, thank you.

anonymous · Answer

When I graph y=2sin(t)cos(t)+ cos(t), it comes out as a straight line.

mertsj · Answer

It is not a straight line.  Did you use a graphing calculator or what?

anonymous · Answer

I used a graphing calculator.

You probably need to expand your range of values.  Try -6 to 6 for the x axis and -2 to 2 for the y axis

anonymous · Answer

It is still showing it as a straight line.
