dsolve('eq1,eq2,...', 'cond1,cond2,...', 'v') symbolically solves the ordinary differential equation(s) specified by eq1, eq2,... using v as the independent variable and the boundary and/or initial condition(s) specified by cond1,cond2,
The default independent variable is t.
The letter D denotes differentiation with respect to the independent variable; with the primary default, this is d/dx. A D followed by a digit denotes repeated differentiation. For example, D2 is d2/dx2. Any character immediately following a differentiation operator is a dependent varia
