Step 1
The characteristic equation is r^2-e^x=0, which has roots r=±sqrt(e^x). Therefore, the homogeneous solution is U_h=C_1e^sqrt(e^x)+C_2e^(-sqrt(e^x)). Show more…

Choose the correct answer: 1) The complementary function of the ODE y'' + y = 0 is Yc = C1cos(x) + C2sin(x) 2) Yc = C1e^x + C2e^(-x) 3) Yc = C1 + C2e^(-x) 4) Yc = (C1 + C2x)e^(-x)

A solution of the equation for the differential equation y'' = 2x(y')^2 is: a. y = ln(c_1 - x^2) + c_2 b. y = ln((c_1 - x) / (c_1 + x)) + c_2 c. y = ln((c_1 + x) / (c_1 - x)) + c_2 d. y = ln(((c_1 + x) / (c_1 - x))^2) + c_2 e. y = ln(((c_1 - x) / (c_1 + x))^2) + c_2
An integrating factor I (x) is found for the linear differential equation (1+x^2) dy/dx + xy = 0, and the equation is rewritten as d/dx (I (x) y) = 0. Which of the following is correct? It is not possible to find such a function I (x)
