    so basically what I had in my head was complete insanity? .. why was I thinkin of ln? Also, why are we "supposing" that x=tan theta? (I get that this is some ancient dervied thing.. but could x have been supposed as anything?)

    Use the iterative formula xn+1 = tan−1(xn + p) to determine x correct to 2 decimal places. Give the result of each iteration to 4 decimal places. how would I know what x1 is?

    [ln (1+x^2)]/2x Its a rule .. integration of 1/x is lnx and in this case you just go back and divide by the differenciation of the inner term hence the division by 2x

    if you got the first part .. then just substitute the values of R and alpha in Rcos(x-a)=2 and then your x=2theta.. so then get theta

    AS MECHANICS p42 is (!!!!!!!!!!!!!!!!!!!!!!!!!), discuss after 24H

    yeh but I screwed up the one on top as well by writing the masses incorrectly, how smart is that?! -_-

    I'm in a rush so I won't do it unless you really need help but substitude e^2x with y

    show me a question.. cause I can't think of any such integration. -_- In fact, check the syllabus and then ask again
