The 4th order of Runge-Kutta method is said to have less accuracy and efficiency than simple Euler's method. True False Given B-4AC=-x', if x>0, then the equation is classified as hyperbolic. True False Euler's method and RK4 method are two of the numerical solutions of ordinary differential equations. True False Minimum point involved in the formula of the central finite difference for second derivative are two points. True False
