mag share na rin ako,.

caltech to solve calculus(indefinite calculus) ung walang limit....no need to memorize all integral calculus formulas.

pati ung pagkuha ng area ng normal distribution curve.. hahaha..

at caltech sa laplace transform..

Okay sir paki share na rin yan dito hehe... Salamat po.

Hello guys.... Eto na uli tayo... Pasensya na at sobrang  tagal ng update ng thread na to. Nawala na kasi ang ginagamit kong calculator eh kaya hindi ko na update to. Sa ngayon nakakita ako ng calculator na 350 MS Casio.Mababa ang model compare sa mga na discuss ko na calculator with the likes of MS 991 or ES 991. Pero sa topic ko ngayon, kayang kaya naman ng model na to na masolve ang given problem natin ngayon. At ang functionalities ng calculator ko ngayon ay present naman  sa mga makabagong model. So lets start


TOPIC: Arithmetic Progression

I. What is Arithmetic Progression

- It is a set of numbers where any two consecutive terms

have a common difference.

E.g.

2 4 6 8 10 12 14


So etong set of numbers na to ay may common difference ng

2 as (4-2 = 2), (12-10 = 2), (8-6 = 2), etc.

So all consecutive terms ay may common difference ng two.

BTW, ano ba ang 'TERMS' pagdating sa arithmetic

progression. Well, eto yun place value ng bawat set of

numbers...

In case dun sa example above,

1st term ng series is 2
Fourth term ng series is 8
Sixth term ng series is 12 and so on.

So alam nyo na rin ang TERM na tinutukoy ko dito.

Gagamitin kasi natin ang terminology na yan sa problem

solving natin.

II. Problem arise with Arithmetic Progression:

- Kalimitan ang problem na may kinalaman sa arithmetic

progression ay kung pang ilan terms si ganito or kung

anong value given ng term sa problem. Pwede rin sila mag

bigay ng "Sum of first five terms of this series" or

alike.

Gamitin natin ang set of example given above:

For example, the problem is:

"The second term of the given arithmetic progression

series is 4 and the fifth term is 10. What is the value

of fourth term?

So kung iaanalyze natin ang given problem, then it could

be like this

x 4 x ? 10

Baka sabihin nyo madali lang hulaan yan, well sa problem

given ko syempre madali lang yan. Pero mag eexpect ka ba

ng ganyan kadali sa exam? kahit tawagin mo ang ilang

santo, hindi ka makakaencounter ng ganyan kadali na

series. Take note na rin, ginawa ko na rin guide yun

given example ko na binigay sa itaas para makapag come up

ng ganyan problem.


III. How to solve the problem:

Conventional way

- Kung high school ka pa lang at binabasa mo to, sorry to

say at hindi kita matuturuan sa kung ano anong formula na

dapat gamitin. Normally, pag kailangan ng solution sa

ganitong problem, kailangan muna malaman kung ano ang

common difference (d) sa given arithmetic progression.

Eto yun mga formula para sa arithmetic progression

an = a1 + (n – 1)d

where

a - value
n - term
a1 - value of first term
d - common difference

So using that formula, you have to extract equations para

makuha mo ang common difference (d). Then pagnakuha mo

na, masosolve mo na ang problem.

Oooops, kung gagawin mo yan sa isang exam where the time

is most valuable i.e. licensure exam then this will be

ineefficient to solve. Baka maglaan ka pa ng 15 mins para

masolve mo to para lang sa 2 points. Tendency pa nyan,

iiskip mo tong problem na to para makahanap pa na mas

madali na questions. Samantala pag calculator lang gamit

mo masosolve mo to ng napakadali.... Paano?

Using calculator:

Sa paggamit ng calculator, though madali lang ang

procedure kailangan pa rin ng konti pag aanalyze...

So ganito ang procedure:

1. Iset as matrix yun given value vs sa given term

for the problem given:

I let x as Value and y as term...

So

x = 4
y = 2 (term)

X = 10
y = 5 (term)

The problem is:

x = ?
y = 4 (term)

Sa calculator..... MS: Go to MODE>>REG>>LIN (linear

regression)

Sa ES, same lang din naman ang procedure, ang pagkakaalam

ko lang instead na makita mo yun mode na LIN pag pinili

mo yun Regression ang makikita mo lang yun sign ng

linear. I think makikita mo ax+b=c (something like that

instead na LIN)....

Moving On...

After na makapasok ka sa Linear regression mode:

Eto po ang gagawin natin:

1. Input 4,2 then press M+. Mag pprompt dyan na n=1

denoting first input
2. Input 10,5 then press M+. Mag pprompt dyan na n=2

denoting second input.

Alam naman natin kung bakit 4,2 ahh dahil sa pag tabulate

natin, we represent x as value and y as term (4 - value,

2 - term) and so on.

3. Since ang nawawala sa pagtatabulate natin ay yun value

ng 4th term. Then yun ang next step natin:

Type 4X^ (di ko makita sa symbol yun x na meron ^ sa

ibabaw :)) )

kung MS makikita yan sa list ng Shift 2 (SVAR) under

linear regression... Sa ES im sure meron din yan...


So pagkatype mo ng 4X^ edi lalabas ang 8.... (viola!!!!!)


Tanong:

Pwede ba namin pagbaligtarin ang pagtatabulate. I.e. x =

term and y = value...

ANS: Pwedeng pwede, as long as hindi ka nalilito sa

pinagagawa mo ahh..... careful baka lalo ka pa mamali...

So paano yun;

x = 2
y = 4

x = 5
y = 10

so ang query:

x = 4
y = ?

so same procedure pa rin...

1. input 2,4 M+ and 5,10 M+
2. then type 4y^, you will arrive with same results which

is 8..

So no need to memorize the given formula... Basta ba may

given ka ng 2 values with 2 terms, masasagot mo na kung

anong value sa pang specific term or pang ilan term given

 the problem value....


try naman natin sa paghahanap ng pang ilan term

Same pa rin ang problem para hindi kayo mawala:

x = 2 (term)
y = 4

x = 5 (term)
y = 10

x = ? (term)
y = 8

so pang ilan term ang 8

same pa rin ang procedure:

1. 2,4 M+ and 5,10 M+
2. Since ang hinahanap ay term then we can type 8x^. The

result is 4 (term)


So kahit term pa ang hinahanap o value no problem yan

dito... Malalaman at malalaman natin yan basta ba bigyan

tayo ng 2 values in two terms.....


For summation of arithmetic progression?

dito ay 50-50.... why? depende kasi sa given problem.

Kung pinapahanap lang sayo ay sum of first 5 terms, or 10

terms ay pwedeng hanaping mo na lahat ng term and

manually na i sum mo sila... Pero kung ang pinapacompute

sayo eh sum of 50 terms, 100 terms so on... then hindi na

sya efficient for that....

kabisaduhin ang formula na to.



So gamit gamit din ng brain cell pag may time  :suka3: :suka3: :suka3:

hanggan sa muli... comment lang kayo pag may mali sa akin
