[ TUT ] MATH - CALCULATOR TECHNIQUEs

[SiRhOSEven]

Hello Symbianizers

Today, I will teach you the Calculator technique use to solve Math problems.
In this tutorial I will be using CASIO fx-991 ES. So don't ask me on how to do it in other calculator.
Moreover, I will not cover the CASIO fx-991 ES PLUS although, some of you think its the same,
I say to you it's different in someway or in some functions especially in STAT MODE.
This is good and very helpful especially in Board Exam and in some school na hindi kinakailangan ng solution(multiple choice lang).
Sa una nahirapan ako dahil iniisip ko kung paano ko isusulat ang mga equation. Ayun nagawan ko naman ng paraan. ​

Requirement in this MATH CALCU tutorial:
1. Basic knowledge in math( You cannot understand it if you don't know the basics..Mostly shorcuts ito kaya you should know the basic..)
2. CASIO FX-991 ES with the manual
3. Read your manual(all the functions and definiton of each will be found in the manual)
4. Brain/Common Sense

You can also post your assignments here..Solve natin yan kung kaya..
Gamitin niyo ang LINK na ito para itype ang mga equation niyo..
Then kunin ang link ng image at ipaste dito gamit ang

Sa mga MATH Wizard diyan, tulong po tayo..hehe



Ok lets get it on!

Session 1 - Part 1

Getting familiar with the functions​

1. What are the roots of the polynomial:

A. -3, -4
B. 6, 2
C. 2, 3
D. 3,4

Set Calculator to equation mode: MODE>5>3 for quadratic equation
Mode 3 because our polynomial is a 2nd degree equation..

Input the equation coefficients a,b,c:
1 = -7 = 1 2 = =

And you will get the answer..

2. What are the roots of the polynomial:

A. 1,2,3
B. 1,2,5
C. 1,2,4
D. 2,3,5

Set Calculator to equation mode: MODE>5>4 for cubic equation
Mode 4 because our polynomial is a 3rd degree equation..

Input the equation coefficients a,b,c:
1 = -7 = 1 4 = -8 = =

And you will get the answer..

3. Which of the following is a possible root of the polynomial:

A. 3
B. 0
C. -2
D. 4

NOTE: A root is any value that, when substituted to the variable(ie x), will satisfy the equation.(In our equation 0=0 )

Set the calculator to computation mode: MODE>1
Input ONLY the left side of the equation.
Trial and error, Use the CALCU function..
Pag nagtanong ang calculator X? iinput ang mga choices..
X? 3 = 
output is 240..
repeat the step until you get an output of 0..
And you will get the answer..

4. Find the value of x and y in the following equations:

A. -12/19, 16/19
B. -24/19, -22/19
C. 12/19, -16/19
D. 24/19, 22/19

Set calculator to equation mode: MODE>5>1 for two-variable equation.

Input the coefficients of a,b and constant c of the first equation:
2 = 3 = 6 =

Input the coefficients of a,b and constant c of the second equation:
-3 = 5 = 2 =

Press the = to get the value of x and press again to get the value of y..
And you will get the answer..

5. The equation

has two rational roots, both of which are positive. Find the larger of these two roots.
A. 1
B. 2
C. 3
D. 4

Same method with number 3..We will be using CALCU function..The calculator should display 0..
And you will get the answer..

6. What is the remainder of the polynomial

when divided by

A. 208
B. 218
C. 283
D. 305

Set the calculator to computation mode: MODE>1
Input the left side of the equation
Apply the Remainder theorem
Use CALCU function and substitute x=5
And you will get the answer..

7. Solve the values of y in the system of equations:

Set the calculator to equation mode: MODE>5>2
Input the coefficients a,b and constant c of the first, second and third equation..
Press the equal = button twice to get the value of y..
And you will get the answer..

8. Solve for the value of

A. 2
B. 2i
C. -2
D. -2i

Set the calculator to computation mode: MODE>1
Input the equation in the calculator(as is)..
and you will get the answer..

9. Solve for the value of

A. 1.91
B. 2.19
C. 1.19
D. 2.91

Set the calculator to computation mode
Input the equation in the calculator(as is)
And you will get the answer..

10. Solve for the value of x in the equation:

A. 1.91
B. 1.19
C. 1.46
D. 2.13

Set the calculator to computation mode
Input the equation and use the SOLVED function to get the value of x..
To get the SOLVED function, SHIFT>CALCU>=
It should display,
X= answer
L-R= 0 (important, must be 0)

And you will get the answer..

CONCLUSION:
Wag niyo ng pag-aralan ang may kinalaman sa pagkuha ng X and Y dahil kaya ito sa calcu using SOLVE and CALC function..

Re: [tut] math - calculator technique

si tolentino ba ang nagturo sau nito?

 

[SiRhOSEven]

Re: [tut] math - calculator technique

hah?..sino yun di ko yun kilala..natutunan ko yan sa school namin dati tapos ngayon sa review center..

 

[bernard005]

Re: [tut] math - calculator technique

ahhh hehe kala ko xa..halimaw kasi un sa ganyan...CE k b?nagtuturo un sa mega review

 

[SiRhOSEven]

Re: [tut] math - calculator technique

ECE ako bro..currently reviewing for my board exam in oct..

 

[zackary]

Re: [tut] math - calculator technique

astig toh wah... ma try sa ibang model ng calcu.

Re: [tut] math - calculator technique

astig toh wah... ma try sa ibang model ng calcu.

sige lang po..kayo bahala..
more will be added soon..may pasok pa kasi ako..

 

[bernard005]

Re: [tut] math - calculator technique

Nice! San k pla ngrereview Bro?Gudluck pre..post mu dn pre ung sa technique sa differential at integral calculus..mdmi gamit un

 

[SiRhOSEven]

Re: [tut] math - calculator technique

yes..of course..lahat yan ipopost ko..in the mean time..basics muna at familiarization sa mga function..hehe..
sa edge bro..ikaw ba?..

 

[bernard005]

Re: [tut] math - calculator technique

Last year pa ako ng board..yan nga ba ung sa tabi ng UST?..EE Ako hehe sa multivector ako dati ng review..wla nagturo smen ng ganyan..kya books lng ni tolentino gamit ko..nagamit ko rn nman ung technique sa ilang problem..nkatulong din tlga

 

[SiRhOSEven]

Re: [tut] math - calculator technique

ah ganun ba..sige pwede mo kami tulungan at sumagot pag may tanong ang mga ka-symbianize natin..

Re: [tut] math - calculator technique

 

[sersi]

Re: [tut] math - calculator technique

kung applicable lang sa mga math test nung high school. kung hindi lang required yung solusyon sa papel.

 

[SiRhOSEven]

Re: [tut] math - calculator technique
