# Lab: 9 # Name: Sydney # I worked on this code with: Sam, Dawit, Carlos # Please do all of your work for this week's lab in this worksheet. If # you wish to create other worksheets for scratch work, you can, but # this is the one that will be graded. You do not need to do anything # to turn in your lab. It will be collected by your TA at the beginning # of (or right before) next week’s lab. # Be sure to clearly label which question you are answering as you go and to # use enough comments that you and the grader can understand your code. #1 var("x,y") plot3d(x^2 + y^2, (x,-10,10), (y,-10,10), axes_labels= ("x", "y"))
