Input:
pdsolve(ds(y,t,2)=2^2*ds(y,x,2))
Write:
`pdsolve(ds(y,t,2)=2^2*ds(y,x,2))`
Compute:
$$pdsolve(\frac{d^{{2}}y}{dt^{{2}}}={2}^{2}\ \frac{d^{{2}}y}{dx^{{2}}})$$
Output:
$$pdsolve(\frac{d^{{2}}y}{dt^{{2}}}={2}^{2}\ \frac{d^{{2}}y}{dx^{{2}}})== C_1+C_2\ t+C_3\ x+C_4\ t\ x\ and\ C_1(C_1+t-\frac{1}{2}\ x)+C_2(C_1+t+\frac{1}{2}\ x)$$
Result: $$C_1+C_2\ t+C_3\ x+C_4\ t\ x\ and\ C_1(C_1+t-\frac{1}{2}\ x)+C_2(C_1+t+\frac{1}{2}\ x)$$
