In Problems 28 through 30, find the first three nonzero terms in each of two linearly independent

Question:

In Problems 28 through 30, find the first three nonzero terms in each of two linearly independent solutions of the form y = Σ cnxⁿ. Substitute known Taylor series for the analytic functions and retain enough terms to compute the necessary coefficients.

(cos x) y'' + y = 0
