Input:
pdsolve(ds(y,t)-ints(y,x)-y-exp(x))

Write:
`pdsolve(ds(y,t)-ints(y,x)-y-exp(x))`


Compute:
$$pdsolve(\frac{dy}{dt} -exp(x)-\int y\ dx-y)$$


Output:
$$pdsolve(\frac{dy}{dt} -exp(x)-\int y\ dx-y)== C_1\ exp(\frac{1}{2}\ t-2.0\ x)-psolution1(-1,-1,-1,exp(x),y,t,x,1)$$ Result: $$C_1\ exp(\frac{1}{2}\ t-2.0\ x)-psolution1(-1,-1,-1,exp(x),y,t,x,1)$$
