dsolve(eq)
dsolve(eq, y)
dsolve(right side of eq, y,x)
dsolve(right side of eq, y,x,n)
dsolve(eq 1, eq 2)
Parameters
eq - equation.
y - default unknown y(x).
x - variable x.
n - the nth order of equation.
Description
For first order differential equation, there are 3 ways to input derivative:
1. y'
2. y(1,x)
3. ds(y) or ds(y,x)
where ds() is a derivative holder.
For second order differential equation, there are 3 ways to input derivative:
1. y''
2. y(2,x)
3. ds(y,x,2)
where y'' is two sinlge quote sign, instead one double quote sign.
For fractional order differential equation, there are 2 ways to input derivative:
1. y(0.5,x)
2. ds(y,x,0.5)
Solution can be tested by odetest(). If odetest(solution,eq) give 0, solution satisfy the equation.
