We completed our class notes on differentials and how they can give us a very good approximation for the change in y only if the change in x is small. We also examined this graphically.
Students also received another worksheet on optimization (8 problems).
The link below has some more worked out examples (scroll down and you'll find them)
HW: Complete the 5 problems on the back of your notes 3.9 and complete the 8 optimization problems on the WS Optimization. Quiz 3.7 (optimization) is Monday, February 2nd.
