冇讀applied...只讀pure...
歡迎大家分享讀pure既心得同經歷

雖然pm係難讀 , 但我讀完一年之後o係大學take d logic or maths related courses whatsoever 已發現自己d mindset係唔同左 , 諗野會critical d ga!

其實Pure Math係乜野黎ga?? 我係加拿大讀中學果陣時淨係得科叫做"Mathmatics", 無香港gum分門別類. Pure Math 係唔係講vector, systeam of linear equation, 同 matrix 果D野啊??

1. Suppose that the recurrence relation is a1=0, a2=1, a n+1 = 1/2 (an+a n-1) n =2,3,4.....
(a) Given that bi= 1-(3ai/2) where i=1,2,3,...,n, find b1, b2, b3.
(b) Hence, guess a formula for the general term of the sequence {ai}and prove it by induction.
(深色係term) (7marks)
2. Suppose p is a prime number not equal to 2, prove that [2*(p-1) -1] / p is an interger. (7marks)
有d唔識打,,,唔知summation個符號

3. Let f(x) = x*4 - 2x*3 - 4x*2 + 6x + 1 and g(x) = x*3 - 5x -3
(a) Show that f(x) and g(x) are relatively prime. (b) Find the polynomials u(x) and v(x) such that u(x) f(x) + v(x) g(x) = 1. (c) Hence, resolve 1/ [(x*4 - 2x*3 - 4x*2 + 6x + 1)(x*3 - 5x -3)] into partial fractions.
