Hi,
My question is based around the idea about calculating the number of possible outcomes when a given number of variables are chosen randomly (all with equal probability of being picked) a given number of times. Most importantly, I an specifically working so that order is redundant. ie AAB =...
can i just mention that that "proof" or process appears increadibly elegant, how long did it take for you to do, could i be so intrusive to ask about you level of expertise as i am taken back by again by the elegence of the solution
cheers
thats great thanks, i knew the general summations but tbh i wouldn't have the wit to make some of those connections, not currently at least...:P
cheers
Hi,
I can't think / remeber how to write the following expresion in a closed form,
the function is a summation of natural numbers between 1 and an upper limit "K", written as
Sigma x with limits K and 1 effectivly, straightforward etc...
what i want is the summation of all the...
agreeing with goldpheonix, the ket is to seterate the initial velocities into components with trig. & depending on question resolving the final velocity at the given time peroid with pythagoras
havn't done projectiles in a while though.
Isn't that just basic SUVAT.
i.e.
v=u+at
v^2=u^2+2as
s=ut+(1/2at^2)
s+vt-(1/2at^2)
where:
a = acceleration (9.81)
u = inital velocity
v = final velocity
t = time
s = displacement
did you guys uses conservation of energy?...why?
