Consider the differential equation,

L[y] = y'' + p(t)y' + q(t)y = 0,

(1) whose coefficients p and q are continuous on some open interval I. Choose some point t0 in I. Let y1 be the solution of equation (1) that also satisfies the initial conditions y(t0) = 1, y'(t0) = 0, and let y2 be the solution of equation (1) that satisfies the initial conditions y(t0) = 0, y'(t0) = 1. Then y1 and y2 form a fundamental set of solutions of equation (1). Find the fundamental set of solutions specified by the theorem above for the given differential equation and initial point. y'' + 7y' − 8y = 0, t0 = 0
