Let's say, hypothetically, I couldn't get the rights to using polar coordinates for this problem soIhad to use the store-brand version where x=rtan,y=rsec. It's called Dr. Polarcoordinates. Instead ofx2+y2=r2 and tan=yx', what would be the two equations for Dr.Polar coordinates? [6 points]We didn't talk about itin class, but there's an arc length formula for polar coordinates too! ItisL=r2+(r')22dUse this to find the length of the entire spiral r=e-a for 0 and a>0.[7 points]We did talk about itin class....it's area of polar curves! Find the area contained within the entirespiral r=e-a for 0 and a>0.[7 points]
