Input:
dsolve(ds(y,x,0.5)-y^2-2y-1)

Write:
`dsolve(ds(y,x,0.5)-y^2-2y-1)`


Compute:
$$dsolve(-1+\frac{d^{{0.5}}y}{dx^{{0.5}}}-2\ y-{y}^{2})$$


Output:
$$dsolve(-1+\frac{d^{{0.5}}y}{dx^{{0.5}}}-2\ y-{y}^{2})== -1+i\ \frac{1}{\sqrt{\pi }}\ (\frac{1}{\sqrt{C_1+x}})$$ Result: $$-1+i\ \frac{1}{\sqrt{\pi }}\ (\frac{1}{\sqrt{C_1+x}})$$
