Hey guys, i was wondering if anyone could help give me iron out some stuff: e.g
locus and parabola for y^2=4ax, is the directrix y=-a and the focus (x+ or - a, y). For some reason i cant grasp the y^2 side despite knowing how the x^2 side works
This may be hard to explain but how would i graph velocity graphs ? I can work out the intercepts and roots, but i get stumped when wondering how to draw them and i dont necessarily have a question on hand
The sum and product of roots and the variations outside of alpha + beta, alpha beta, there is one of them which i cant exactly remember ( which i know isnt helpful in trying to get help for) but its a more 'complex' one that requires a bit more algebraic manipulation
Thanks
