Ah, you're just writing this because I yelled out, "s**2 * sin (a)" and "Laplace transformation" and "dx/dt (x**2) = 2x" this morning before settling in on "Square Root of -PI!!!!" That is no more imaginary than "Oh God!" 
Squares of imaginary numbers are complex, just like life. Almost everything is part real and part imaginary.
