test the sets of matrices for linear independence in M22. For those that are linearly dependent, express one of the matrices as a linear combination of the others.

L27 - 5 Caution: You must have an indeterminate form to use L’Hoˆpital’s Rule! cosx + x ex. Find the limit: liπ x→2 sinx x ex. Evaluate: lim 1+ e x→0 + lnx
