Input:
pdsolve(ds(y,t,2)-ds(y,x,2)-ds(y,x)-exp(t )-exp(x))
Write:
`pdsolve(ds(y,t,2)-ds(y,x,2)-ds(y,x)-exp(t )-exp(x))`
Compute:
$$pdsolve((-\frac{dy}{dx} )-\frac{d^{{2}}y}{dx^{{2}}}+\frac{d^{{2}}y}{dt^{{2}}}-exp(t)-exp(x))$$
Output:
$$pdsolve((-\frac{dy}{dx} )-\frac{d^{{2}}y}{dx^{{2}}}+\frac{d^{{2}}y}{dt^{{2}}}-exp(t)-exp(x))== C_2+exp(t)-\frac{1}{2}\ exp(x)+C_3\ exp((-x))+C_1\ (\frac{1}{2}\ {t}^{2}+x)\ and\ C_2+exp(t)-\frac{1}{2}\ exp(x)+C_1\ exp((\frac{-1}{2})\ x)\ E_{2} ((\frac{-1}{4})\ {t}^{2})$$
Result: $$C_2+exp(t)-\frac{1}{2}\ exp(x)+C_3\ exp((-x))+C_1\ (\frac{1}{2}\ {t}^{2}+x)\ and\ C_2+exp(t)-\frac{1}{2}\ exp(x)+C_1\ exp((\frac{-1}{2})\ x)\ E_{2} ((\frac{-1}{4})\ {t}^{2})$$
