Does anyone think there's gonna be a circle theorem proof question this year? I hate the idea of memorising and regurgitating these so much and I don't want to have to put too much effort into doing so if I can use that to focus on everything else instead.

anyone have any iteration resources/examples and would be happy to explain?

i have no resources but ill give explaining a shot: you do iteration when you have an equation and you want to find a value of x exactly but you have a vague idea of what x might be. iteration is usually a calculator topic. so you put your estimated value of x into your calculator and press equal. your x value is now stored in the Ans button. so you rearrange your equation in such a way so that it is equal to x. it doesnt matter if there are x's on both sides because we'll come to that later. say we have the equation x^3−9x^2+27x−27=0. we can rearrange so that x^3 = 9x^2 - 27x + 27 and then cube root both sides so we get: x = cube root(9x^2 - 27x + 27). our estimated x value is called x0. i will say (for example), x0 = 2 because i think that could be a solution. x0 is given in the exam. now in our rearranged cubic equation, we just substitute x with the Ans button (x = 9Ans^2 - 27Ans + 7). you will get a number answer. that is x1. press equal button again. that is x2. if the question does not specify till what x value to keep on iterating, do until the answer no longer changes when you press =. if it does, i will say in the question x4 is wanted as an answer. record the value of x0, x1, x2, x3, x4 on your paper because iteration questions want working. in the end after iterating, i got the answer of x4 = 3.975 (3dp). did you get that? according to google, apparently, the answer is 3. so we are quite close. usually, when you do iteration, the more you do it, the closer you get to the answer. but this is not always the case (as seen in this equation, if you continue to iterate it). feel free to correct me anyone 🙂 just my 2 cents

use maths genie , they have worksheets asw a video explaining how they got the naswer

tysm, what happens if it is non-calc

guys can someone plz help with this qu

for a sec i thought this was furthermaths 😭 basically the domain of a function is the set of all possible input values aka the x values that u can substitute into the function without breaking any mathematical rules eg dividing by zero which would give u an undefined answer. u look at the denominator of the function, set it equal to zero, and solve which would be 3/4

its not fm!? i swr this is, i dont remember learning this in normal maths, only fm...

thank youuu so would you always set the denominator to 0 in qus like those

guys can someone plz help with this qu

lowk ive never seen something like this in normal maths tbh can u show me where u got this qs from? but yeah usually when the equation for a function its a fraction and it asks you what cant be in the domain, it always the x value where if u did input it the denominator would equal to zero because the answer would be undefined so it wouldnt give u an answer for f(x)/y (lowk yapping but i hope this makes sense lmao 😭)
