### MATLAB: How to applay y”'+y'=0 , y(0)=y0=0, y'(0)=y01=1, y”(0)=y011=-2 in the following system where fn=y”' i got differential equationssolve dy = diff(y ).

y 2 dx + (xy + x 2)dy = 0 From Equation (1.1.12) we have c = y2 x, which, when substituted into Equation (1.1.13), yields dy dx = y 2x. Consequently, the slope of the given family at the point (x,y) is f(x,y)= y 2x, so that the orthogonal trajectories are obtained by solving the differential equation dy dx =− 2x y. Verification of a Solution and Differential Equation: Verifying a solution means substituting it into the given equation and performing all the respective operations to verify that the equality is Se hela listan på mathsisfun.com Se hela listan på intmath.com separable\:y'=\frac {xy^3} {\sqrt {1+x^2}} separable\:y'=\frac {xy^3} {\sqrt {1+x^2}},\:y (0)=-1. separable\:y'=\frac {3x^2+4x-4} {2y-4},\:y (1)=3.
