Sketch some level curves of the function max( | x | , | y | ). (b) (10 pts.) Find a function whose level curves are the same as in (a), but rotated 45 ◦ . B.3) (After Sept. 21, 10 pts.) Use the tangent plane approximation formula to estimate the root of x 2-5 . 99 x + 8 . 02 close to 4 without using a calculator . Then use a calculator to ﬁnd the root to 5 places after the decimal point. Reminder: Please write “Sources consulted: none” at the top of your homework, or list your (animate and inanimate) sources.
