ทำไมคณิตสาสตร์ต้องใช้ X , Y ในคณิตศาสตร์ สมมุติฐานเบื้องต้น
1. เขียนง่าย สองขีดแทยงมุม จบ ลองนึกว่าต้องแก้สมการยาวเป็นหน้า คนนึงเขียน X, Y อีกคนเขียน E, W ในจำนวนเท่ากัน
2. คำในภาษาอังกฤษที่ขึ้นต้นด้วยตัว X Y Z มีน้อยมาก จึงใช้แทน"Unknown" หรือ "ตัวไม่ทราบค่า" ในขณะที่ตัวอื่นๆ เก็บไว้เขียนตัวย่อของปริมาณอื่นๆ ที่มีคำบัญญัติไว้แล้ว เช่น D = S*T D = distance , S = Speed , T = time หรือเป็นค่าคงที่ c, k
There's no combination of words I could put on the back of a postcard No song that I could sing But I can try for your heart Our dreams, and they are made out of real things Like a, shoebox of photographs With sepiatone loving Love is the answer, At least for most of the questions in my heart Like why are we here? And where do we go? And how come it's so hard? It's not always easy and Sometimes life can be deceiving I'll tell you one thing it's always better when we're together
[Chorus:] MMM it's always better when we're together Yeah, we'll look at the stars when we're together Well, it's always better when we're together Yeah, it's always better when we're together
And all of these moments Just might find their way into my dreams tonight But I know that they'll be gone When the morning light sings And brings new things For tomorrow night you see That they'll be gone too Too many things I have to do But if all of these dreams might find their way Into my day to day scene I'd be under the impression I was somewhere in between With only two Just me and you Not so many things we got to do Or places we got to be We'll Sit beneath the mango tree now
It's always better when we're together Mmmm, we're somewhere in between together Well, it's always better when we're together Yeah, it's always better when we're together
MMmmmm MMMmmmm Mmmmmm I believe in memories They look so, so pretty when I sleep Hey now, and when I wake up, You look so pretty sleeping next to me But there is not enough time, And there is no, no song I could sing And there is no, combination of words I could say But I will still tell you one thing We're better together.
