================================================
2. Given a1 = -9, a2 = -4, such that an = a(n-1) - a(n-2). Calculate sum of
first 100 terms?
Note: (Here 1, 2, (n – 1) and (n – 2) are suffixes)
這題我算出來是9,可是寄託答案就有-19和1。請教大家有人會這題嗎?
3. If (1/(x + y)) – 1 + (1/(x - y)) -1= 4, then which one of the following
must be true?
I. x = 2
II. y = 0
III. y = -1
& so on…..
這題我化簡後就解不出來了? 有沒有人會這題?韓國那檔案的解法,後面有點怪
寄託那邊有人算出X=2
5. There is a micro chip. Each side is extended by 0.1 millimeters.
If surface area of one face increases to 0.75 mm, find the original length of
the edges? (Similar to this)
6. Given k1 = 1. The series is such that ki = 5k(n-1) + 4. Find the least
possible value of ‘i' for which ki is divisible by 7?
Note: 1, i and (n-1) are subscripts.
我這題看不懂他的意思@@
7. If -6 <= x <= 4 and -10 <= y <= 4,
then what is the greatest value of (–x^2 + y^4)?
A. 16
B. 240
C. 10,000
D. 10,036
& so on……………
這題我覺得怪怪的,不知道大家是怎麼算的? 印度數學算出是C,我算是D,拜託大家了。
9. Given the dimensions of a triangle as 5, 6 and 8. If the angles opposite
to sides 5 and 6 are ‘x’ and ‘y’, then
Col A: The third angle
Col B: 90
以上是我算錯和不會的,有沒有人最近有算過這份10/16印度機經,可以教我一下嗎?
提供個詳解,感謝~
