Solve the initial value problem 2yy' + 2 = y2 + 2x with y(0) = 4. To solve this, we should use the substitution u = With this substitution, y = y' = Enter derivatives using prime notation (e.g., you would enter y' for dy/dx). After the substitution from the previous part, we obtain the following linear differential equation in x, u, u'. The solution to the original initial value problem is described by the following equation in x, y.

1. Begin by making the substitution u=ex . The resulting
integral should be ripe for a trig substitution.
2. Make a choice of trig substitution based on the ±a2±b2u2 term
you see after the substitution. With the right choice, after
substituting and rewriting using sin/cos, you should again have
something fairly nice to solve as a trig integral.
3. The substitution sin(2θ)=2sin(θ)cos(θ) is useful after you
integrate.
