Can this be simlified?

    Can this be simPlified?:rofl:

    A = B - sin(degtorad(C)) * sqrt(abs(sqr(D/2) - sqr(sqrt(sqr(E - F) + sqr(B - G))/2)))

    A, B, C, D, E, F, G are variables. I don't need to simlify down to a numerical value of a variable just now; I'm just wondering if the equation can be simplified.

    Other terms
    degtorad() means the amount inside the paranthese is converted from degrees to radians.
    radtodeg() converts radians to degrees.
    abs() means absolute value
    sqr() and sqrt() are square and square root

    Well, there's the obvious point that
    sqr(sqrt(sqrt(sqr(E - F) + sqr(B - G))/2)= (sqrt(sqr(E - F) + sqr(B - G))/4
    That is, that
    [tex]\frac{\left(\sqrt{(E-F)^2+ \sqrt{B-G}}\right)^2}{2}= \frac{\sqrt{(E-F)^2+ \sqrt{B-G}}}{4}[/tex]
