Input:
pdsolve(ds(y,t,2)-a^2*ds(y,x,2)-a^2*ds(y,u,2))

Write:
`pdsolve(ds(y,t,2)-a^2*ds(y,x,2)-a^2*ds(y,u,2))`



Compute: $$pdsolve(\frac{d^{{2}}y}{dt^{{2}}}-{a}^{2}\ \frac{d^{{2}}y}{dx^{{2}}}-{a}^{2}\ \frac{d^{{2}}y}{du^{{2}}})$$

Output: $$ pdsolve(\frac{d^{{2}}y}{dt^{{2}}}-{a}^{2}\ \frac{d^{{2}}y}{dx^{{2}}}-{a}^{2}\ \frac{d^{{2}}y}{du^{{2}}}) == 2\ c_1+c_2\ u+c_2\ x+C_1\ ((-0.5)\ \frac{1}{a^2}\ {u}^{2}+0.5\ \frac{1}{a^2}\ {x}^{2})+C_1\ ((-0.5)\ {a}^{2}\ {u}^{2}+0.5\ {a}^{2}\ {x}^{2})+0.5\ \frac{1}{a^2}\ {x}^{2}\ y^{(2)}(t) $$ Result:$$2\ c_1+c_2\ u+c_2\ x+C_1\ ((-0.5)\ \frac{1}{a^2}\ {u}^{2}+0.5\ \frac{1}{a^2}\ {x}^{2})+C_1\ ((-0.5)\ {a}^{2}\ {u}^{2}+0.5\ {a}^{2}\ {x}^{2})+0.5\ \frac{1}{a^2}\ {x}^{2}\ y^{(2)}(t)$$
