- Error Analysis Danielle tests the following conjecture.
If two angles share a common
vertex, then they are adjacent.
Her work is shown below. What error does
Danielle make?

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0
