When solving partial fractions, in 10 (i) , how do we get A and B as 2?
Dont worry about that, at last your expression will be the same as the answer.
but I get both A and B as 1/1800
why?
I get the same, eventually, at last i got same expression. 3600/1800 will at last be 2, so its one and the same thing.but I get both A and B as 1/1800
Thank you so much!5(ii)
Take any random value for a in the iterations. For example, 2.34567 then insert that in the a, then keep repeating till u get converging value, that will be your alpha, it will converge to 1.477.
6(b)
10 + 3(-1) = 7 least
10 + 3(1) = 13 greatest
Least value of cos is -1 and greatest is 1.
7(i)
use quotient rule to solve it, and simplify it to get in the form asked.

*error in the pic* : in the first step, its y = expression.
That expression if u try, wont give any value after some value maybe 4 or 5, try it, calc will show an error.Thank you so much!
For the formula, that means I can use any value as an initial value, e.g 3 or 7 or 10?
And for the greatest and lowest value, why can't I replace it into the expression 10+(5)^1/2 cos x-sin x itself? Shouldn't it give the same answer?
Never mind....Thank you again for your help!That expression if u try, wont give any value after some value maybe 4 or 5, try it, calc will show an error.
Lol, i dont know that..
Well yes, how can u even do that with that equation?? xDNever mind....Thank you again for your help!
In ms its written that 2 or equivalent. So dont worry, your marks wont be deducted if u ggot final answer similar to that in ms.but I get both A and B as 1/1800
Well ...I thought of replacing the highest and lowest value of both sin and cos
The complex numbers needs instruments which i dont have with me atm, as soon as i go home i will do it, well one question is attached which may be confusing, i will post that again too if u dont get it, do check my answers the pictures attached are in order wise , first question is for techgeek and rest for isean97Need help with these following: M/J/16 Questions for Vectors and Complex Number.
I'm really bad at these two topics.

May I ask, the Parallelogram
Just make argand digram like any simple graph thats it, and plot the points as given.
