donor y did u start the wind vector from the tail of Vpw vector???
y didn't u start from the origin???

Re: O'level Maths, Addmaths and Statistics help available he

because Vp=Vp/w + Vw
if i did wat u say than the answer would be wrong

How do we draw graphs of Sine and cosine?
I mean what the difference.
If equation is given!
amplitude and period. That stuff?
Please tomorrows paper

Re: O'level Maths, Addmaths and Statistics help available he

aSin2Θ + b
For this equation, a is the amplitude. 2Θ=360. Θ=180 is the period and b is the line of axis, which you take as the starting line.

 

[Asad]

Re: O'level Maths, Addmaths and Statistics help available he

Same for cosine?
And if they ask us to find this equation from graph then?

here 1 +2sin2x , is the amplitude (1+2) = 3 or just 2?

 

[OakMoon!]

Re: O'level Maths, Addmaths and Statistics help available he

Sorry, couldn't reply earlier.
The amplitude will be 2 but the maximum and minimum points will be 1+2=3 and 1-2=-1, respectively.

Re: O'level Maths, Addmaths and Statistics help available he

It's not a BIG problem. You have good enough time to prepare for the Statistics exam, that won't require any time more than two months. With one month for the course and the other month for the past papers. Tell us which city you live in, so that we can advice you an academy because help would be required to understand a few concepts. For a book, visit the local book shop or check the resource list in the statistics syllabus and get the book.
