dsolve Symbolic solution of ordinary differential equations. dsolve will not accept equations as strings in a future release. Use symbolic expressions or sym objects instead. For example, use syms y(t): dsolve(diff(y)==y) instead of dsolve("Dy-y). Example 1: Solve y' = y, y(0) = 2 syms x y(x) dy(x) = diff(y); Y = dsolve (dy==y,y(0)==2); Example 2: Solvex=x√1-² syms x y(x) dy(x) = diff(y); Y = dsolve (dy==x*sqrt(1-y^2)); Exercises: Solve the following differential equations 1. (1+x) y - xy=x+x² 2. dx+y=x, y(0) = 4 3. dy +ySeCx= C0$t
