I received 6/10 points on this assignment. Here was my work.
with p(t) given and I need to evaluate it at 1000 hares. I just set the equation equal to 1,000 with gave me
1000=1500*cos(pi/60(t-30))+2000. and all of this reduced down to the following in the end
-1000/1500=cos(pi/60(t-30)) followed by
cos^-1(-1000/1500) but clearly I am missing something here as I only received 6/10 and I kinda think that was pitty points >.<
Or should I have done something as simple as following the 1,000 line i drew across the graph and just found where it intersected and get my population from that.
