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

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 :)

What is the best way to revise for chemistry alevel?

First go through and make sure you understand the content. A-Level Chemistry is very big on concepts! Then, and I really can't stress this enough, do as many questions as possible. Chemistry is an applied science, memorising alone won't really get you far. By answering questions you'll understand what details you've missed out and the overall language + keywords they want you to use in your exam.

W=3(2a+b)-4 make a the subject?

Expand the bracket first by multiplying the number on the outside with each term on the inside: W = 6a + 3b - 4 Now shit the terms that don't include "a", making sure to do the inverse on the other side : W - 3b + 4 = 6a Now move the 6: (W - 3b + 4) / 6 = a

Describe the structure of lithium chloride?

First off, do you know what type of bonding is in lithium chloride? Since it’s made of a metal and a non-metal, it’s gonna be ionic bonding. Which means electrons are being transferred from one atom to another right? Which atom is going to lose electrons and which will gain, and how many? Lithium, being in group 1 has 1 electron in the outer shell. Chlorine in group 7 will have 7 electrons in t... more

How do I know what is the best way to revise for me?

Try different techniques! I revised best by answering questions and learning from the mistakes I made. Which I would definitely suggest for all subjects, especially for those that are very application driven (Maths and Sciences). For things that require more memory and recall, see what works for you. Mind maps, flash cards, summarised notes, flow charts; all good ways to help you retain informat... more
