Input:
pdsolve(ds(y,x,2)--ds(y,u,2)--ds(y,v,2)=0)

Write:
`pdsolve(ds(y,x,2)--ds(y,u,2)--ds(y,v,2)=0)`


Compute:
$$pdsolve(\frac{d^{{2}}y}{dx^{{2}}}+\frac{d^{{2}}y}{du^{{2}}}+\frac{d^{{2}}y}{dv^{{2}}}=0)$$

Output:
$$pdsolve(\frac{d^{{2}}y}{dx^{{2}}}+\frac{d^{{2}}y}{du^{{2}}}+\frac{d^{{2}}y}{dv^{{2}}}=0)== 2\ C_1+C_2\ v+C_2\ x+C_4\ v\ x+C_3\ (\frac{1}{2}\ {v}^{2}-\frac{1}{2}\ {x}^{2})-0.5\ {v}^{2}\ y^{(2)}(u)$$


Result: $$2\ C_1+C_2\ v+C_2\ x+C_4\ v\ x+C_3\ (\frac{1}{2}\ {v}^{2}-\frac{1}{2}\ {x}^{2})-0.5\ {v}^{2}\ y^{(2)}(u)$$
