It becomes much clear when you think about number lines. Especially with negative numbers and letters. Here is an example of number lines: Number lines

Hi all, How would you determine the angle i in the following equilateral triangle. Thank you.

Hi, I think you can by using the table, the phase difference formula and trigonometry. I have tried that but I don't get the right answer.

Hi all, This is not homework or coursework. I am not sure whether this question would be classed as homework or coursework because it is neither. I am using the AQA Physics A AS textbook and attempting exercise 12.2 on page 177. In I am stuck on question 4 and I have absolutely no idea on...

Hi all, I have found this formula being used but I am not sure what it means. It is used to find the radius of a circle in a sector. Hope you can help me understand it. sin(π/6) = r/(6-r) r is the radius of the circle itself and 6 is the radius of the sector or the circle of the sector...

Is there a way of working it out without getting fractions when using long division? I know the factor will be: (x)^2 / 3

Hi, I have tried that but it won't work without leaving decimals/fractions. I will am using long division.

Because I have not really came across a problem like this I am finding it even difficult to think about the factor. An example will enlighten me. How about powering it (3x)^3 and divide by 9. (3x)^3 / 9 That would not work, would it?

Hi, What I have posted is actually part of the question. This is not homework. I have worked through the all question, I forgot to mention that I was stuck at that point and gave it a lot of thought but could not think through it.

Hi all, Please help understand how this works out. I know how to work it out when 3x-1 has no 3 ie: x-1. Divide x^3+4x^2+3x by 3x-1 Thank you

Hi all, Could you confirm this for me please. I am revising S1 statistics. P(A' u B) = P(B) + P(A' u B') Is that true? I assume you can represent that on a venn diagram. Is that true. I am having trouble understanding the equations which contain ' such as P(A' n B). Thank you.

Do all nuclei have equal number of protons and electrons therefore are not charged at all. I mean when they initially they write the atom symbol showing the atomic number and nucleon number without showing the number of electrons.

Hi all, I am having trouble understanding how to calculate specific charge. I know that it is charge/mass. But what charge are they referring to? For instance an atom may be charged + or - and may not be charged at all. In that instance are we referring to the extra charge that exceeds the...

Thanks that helped a lot!

Thanks for the reply you've cleared up a few gaps. I am unable yet to imagine when the question asks; ...an object is moving in the direction vector; 3i -4j. What does that mean about the position of the object? Has the object moved? or Is it the distance to be covered? I have trained myself to...
