    Why does my diagram not work


    Posted from TSR Mobile
    I am pretty tired but a brief look at it seems like you have drawn the right angle in the wrong place. I will do the question in school today.

    What proofs do we need to know? I'm worried a proof will come up but I've only seen trigonometric proofs which are from C3.

    Thanks i think you're right but i don't get why it's in the wrong place so that I can avoid making the same mistake next time.

    So what is the question? The full question please. Where is the trouble occuring? All I see is rearranging for C the plugging in x and y as given. Then rearrange for y using logarithms.

    So this is the question number 20. I did it and got down to the equation in the picture. But what I don't get is If I try to rearrange for y and then work out c I get c=0. Which is wrong I think.

    Also with the equation you linked. I get C=5/3

    C4 Vectors are just frustrating. It's a lot harder than M1 Vectors but I can't seem to get to 100% grips with it yet. Anyone else in the same boat?

    I've got my C4 Mock next week Friday on 8th May. Has everybody already sat their C4 mock exam yet?
    I think my class is super slow at finishing the content.

    I have my C4 mock exam on 12th May. Still need to improve on vectors We've finished the content.

    What are you learning at the moment in class do you mind me asking?
    Have you had any other mocks i.e m1-2/s1-2?

    With vectors just keep practising as the questions are very repetitive and even if the oddball comes up having experience with help. Physics&maths tutor has put together a vectors question pack if you really want to hammer this topic: https://7ffbf36f16de0198415331fba278...%20Vectors.pdf
