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

Thanks

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
$$\frac{\left(\sqrt{(E-F)^2+ \sqrt{B-G}}\right)^2}{2}= \frac{\sqrt{(E-F)^2+ \sqrt{B-G}}}{4}$$
