    Can somebody give me a quick recap of the formulas and rules for projectile questions? just the basic stuff, I only took it up this year. I know all the formulas etc. just looking for all the "Si when sj=0" or whatever they are :)

    I'm not sure what you're asking for. Are you looking for the derivations of max range and max height, angle where max range equals max height etc.?

    Max height: Sj when Vj=0
    Range: Si when Sj=0 (you will get two values for t, one will be zero, the other will be the one you're interested in)
    Landing angle: Tan L = |vj/vi| (where || indicates absolute value/modulus)

    Given a particle is projected at speed u, and at an angle A, the vector u is ucosAi + usinAj

    Hope this helps
