Input:
dsolve(x(0.5,t)=x,y(0.5,t)=x-y)
Write:
`dsolve(x(0.5,t)=x,y(0.5,t)=x-y)`
Compute:
$$dsolve(x^{(0.5)}(t)=x,y^{(0.5)}(t)=x - y)$$
Output:
$$dsolve(x^{(0.5)}(t)=x,y^{(0.5)}(t)=x - y)== x=exp(C_1+t), y=\frac{1}{2}\ exp(C_1+t)+C_1\ E_{0.5} ((-\sqrt{t}))$$
Result: $$x=exp(C_1+t), y=\frac{1}{2}\ exp(C_1+t)+C_1\ E_{0.5} ((-\sqrt{t}))$$
