the formula is:

T = 2pi sqrt(L/g)

how is that rearranged to find g?

I got g^2=2piL / T

is that right? thanks

g = ((L)/((T)/(2pi))^2)

PIML,

You forgot to square the 2*pi

e.g. if a = 1/b, then multiplying on both sides by b gives

ab = b/b = 1

ab = 1.

Similar for multiplication and to invert square root, simply square both sides.
