1. The problem statement, all variables and given/known data What's the general procedure for solving an i.v. b.v. ode of the form (d^2 T(x))/ (d x^2) = -c * e^T(x) T(+/-1) = 0 T'(0) = 0 where c is a constant 2. Relevant equations i know from ode class that problems like this can usually be evaluated as T'' + k^2*T = 0 3. The attempt at a solution whats throwing me off is the e^T(x) can i make a substitution like. T(x) = ln(y(x)) and solve (d^2 ln(y(x))/ (d x^2) + c * y = 0 and ln(y)'' + sqrt(c)^2 * y = 0 thanks and solve for y? or is this a violation?
