Basically we had an experiment where we had to change the distance 'd' on a v shaped pendulum (0.5d for each side of the V)..where the value 's' which is the hypotenuse distance of the V stayed constant but the vertical distance changed.

does the following formula hold:- we know T = 2pi√L/g

now for this experiment using pythagorus' theorem we can find that L = s^2 - 0.25d^2

which gives T = 2pi√√s^2 - 0.25d^2 / g

is this correct and does the equation hold.

also what other things can i talk about to analyse V-shaped pendulums in particular, I have to write a long essay on it. and was wondering what else i could say the experiment.

Thanks a lot
