For each of the matrices in Exercises 1 through 18, find aU(real) eigenvalues. Then find a basis of each eigenspace, and find an eigenbasis, if you can. Do not use technology.

L22 - 5 Diﬀerentials Def. Let y = f(x)b eaieaelni. The diﬀerential dx is an independent variable (it can be any real number). The diﬀerential dy or d(f(x)) is a dependent variable deﬁned by x ex. 1) Find dy if y = f(x)= 2. 3 − x 2) Evaluate dy when x =2a nd dx = −0.02.
