So let's get back to the topic, is there a lot of theory in Physics AS/A2?

So let's get back to the topic, is there a lot of theory in Physics AS/A2?

its ln|x-1| + C and as the previous replier said don't forget to put the absolute value symbol around x-1 because the absolute value is here f(y)=f(-y) which means that ln|x-1|=ln|1-x|

I still think its dodgy because you are producing 3 OH so need 9 like in electrolysis, where 2O2-→4e- + O2 on the principle of that it should be 9 but I'm thinking the question itself is incorrect because it should be 3Cr3++9OH-→Cr(OH)3

I'm doing Maths and Further Maths, which includes M1-M3.

Cr3++?OH-→ Cr(OH)3 I think it should be 9 but the mark scheme says 3 but accept correct multiples because the 3+ charge has to be canceled by 3- and this has to produce 3 O

I'm at GCSE and it is likely that I'm doing AQA Physics because when my sister did Chemistry and Biology they with AQA but things change and I don't know which spec anyway and I have looked at the specs and didn't really like A but thought B looked very mathematical and doable, once I've studied...

I don't have to take Physics in any way-its just that Physics would open up many doors and I could do really well in it because I'm good at Maths and I want to do more maths as well and it would be so good to investigate things like relativity as a job and all the very best mathematicians became...

I'm not too good at Physics generally, I scrapped a B on unit 1 initially and then just scrapped an A in the resit of unit 1 but I have heard the a-level includes a lot of maths but I'm not sure whether to do the A-Level because I'm not really good at Science, particularly physics and...

I think I get it now because you can't change one thing and keep 2 other things constant.

I'm confused over this because generally I'm told that if the voltage increases then so does current and this satisfies the equation:V=IR because I=V/R increasing the top of the fraction should mean that the current increases but this contradicts the equation:P=IV be=P/cause this time I=P/V and...

Think about it like this what is √4-√1=1 obviously what is √7-√4, √9-√4=1 so less than 1, which means that the difference between higher roots is less than lower roots-you could also think that there are more roots to share between 2 numbers higher up eg.√100 to √81, for 9-10 and √4-√1, for 2-1...

Is there a rin(x) calculator on the internet?

Can you go through the notation because I don't understand it and is there a calculator on the internet for them, with degrees and radians?One of the reasons, I have asked this is that I have discovered some nice theorems to approximate such functions where x is in degrees,sin[2]x=sin sin x...

You are on the right lines but your link doesn't include any information on that specific equation.
