V=u+at u=3 a=-2 t= 1/4

Re-write the original equation: v = u + at, except now with the numbers they've given for each letter: v = 3 + (-2 * 1/4) ---> [Remember in algebra, two letter next to each other have a multiply in between them!] Now we simplify using BIDMAS: v = 3 + (-1/2) v = 3 - 1/2 v = 2 1/2 or 2.5 :)

How do I do differential equations?

Initially, your equation will include dy/dx = (...) right? Inside the (...) will be an "x" term and a "y" term. For example: dy/dx = x/(1 + y). Rearrange that so your "y" term is with dy and your "x" term is with dx: (1+y) dy = x dx Integrate each side! y + (y^2/2) = x^2/2 + c ---> [the (+ c) only needs to be on one side, I prefer the left.] What you do from here depends on your question s... more
