Salamat sa pagtitiwala..Pero bakit hindi mo po nilagyan ng direction..
Hindi ko tuloy alam gagawin ko..pero hulaan ko ito, order of operation ito..
Alam mo po ba yung PEMDAS?..yaan po ang gagamitin niyo sa pagsolved niyan..Ito po ang order of operation.. P arenthesis E xponent(Power and roots) M ultiply D ivide A dd S ubtract
To solved your assignment, use PEMDAS..First perform the operation inside the Parenthesis..Next, the exponents(power or roots, etc).. Next, Multiplication and Division from left to right..lastly Add and Substract from left to right..

Ano pong gagawin natin diyan?..
be specific naman..naguguluhan kasi ako sa mga sinasabi mo..
Remind ko lang po na pakibasa po ulit ang Forum Rules before posting..Baka magkaaward ka sir..Forum Advisor ka pa naman.. 8. Re: [ TUT ] MATH CALCULATOR TECHNIQUEs
wow..
da best to..ngayon ko lang naintindihan ang binary..

It's not about putting words into sentences, or making sentences into stanzas. Writing is about how you put your heart into your works.
9. Session 2 Part 3 SESSION 2 PART 3
21. Find the
A.
B.
C.
D.
Code: Remember, in solving Trigonometric or inverse trigonometric, use RADIAN MODE.. Lagyan ng limits from 0 to 1 then press = Makakakuha ka ng sagot..I‐note ito.. i‐substitute ang limits sa choices..Wag intindihin ang constant "C"..remember, upper limit minus lower limit..lets say for example sa choice A..
Pag pumarehas ang sagot mo kanina(yung ni‐note mo) yun ang sagot.. Happy integrating..;)
22. Find the centroid of the area bounded by the parabolas
and
A. (1.8, 1.8) B. (1.9, 1.9) C. (2,2) D. (2.1, 2.1) Code: Shorcuts lang ang ibibigay ko since ito ay calculator technique.. Given:
Pag nakita niyo na parehas yan, i mean 4x,4x...6x,6y...8x,8y...9x,9y and so on, ang shortcut niyan is 0.9x(center): therefore, 0.9 x (2,2) = answer
23. Find the area of the region bounded by
, the xaxis, and the vertical lines x=0 and x=4.. A. 5 sq. units B. 16/3 sq. units C. 17/3 sq. units D. 6sq. units Code: First get the limits from the equation it self..Use EQN 3.. X=3 and X=2
Pasensiya na po kayo sa drawing ko..hirap e..Ayun bale alternating po yan.. Then integrate using the limits..
Kaya po negative yung isa kasi dumaan po sa negative half cycle.. And you will get the answer..
24. Determine the area of the region bounded by the curve
and the xaxis,
A. 2.25 sq. units B. 2.5 sq. units C. 3 sq. units D. 37/12 sq. units Code: Get the limits from the equation..Use EQN 4..
Ang you will get the answer..
25. Find the lenght of arc of the curve y = ln cosx from x=0 to x=pi/4.. A. 0.65 B. 0.72 C. 0.81 D. 0.88 Code: Kung alam niyo formula gamit ang long method, go..Di ko na siya ibibigay..Shortcuts lang lahat ito.. Ang shortcut dito ay distance formula(two points).. First get the functions of y=f(x) When x=0, x=pi/4 Then y=0, ‐0.34 Then use the distance formula..
And you will get the answer..
26. The speed of the particle is given by
. What distance does it travel while its speed increases from 7 to 99 ft/s? A. 83.3 ft B. 90 ft C. 96.7 ft D. 100 ft Code: Get the limits from the equation when d=7..Use EQN 4.. 2 5 0 ‐7 Get the real number and that is your lower limit.. Get the limits from the equation when d=99..Use EQN 4.. 2 5 0 ‐99 Get the real number and that is your upper limit..
Then integrate the equation using your lower and upper limit.. And you will get the answer..
27. Solve for the general solution of the differential equation:
A.
B.
C.
D.
Code: Get the roots..Use EQN 4..1 0 0 8 You will get one real root and two complex roots.. KEY: Pag real root =
Pag complex root = sin and cos
28. Solved for the particular solution of the differential equation: x + y dy/dx = 2 when x=1 and y=1 A.
B.
C.
D.
Code: Choice one from the choices and Convert the equation to y=f(x).. Differentiate using your calculator with x=1(as given) and you will get the value of dy/dx Substitute x, y and dy/dx to the equation in the problem and see if it is equal to 2... 2=2
If yes, then your choice is the right answer..
29. Solve for the general solution of the differential equation y'y = 2.. A.
B.
C.
D. Code: Choose one in the choices.. Choose your favorite number for C and x and substitute it to your choice.. And solved for y..i‐note.. i‐differentiate ang iyong napiling equation with x=(kung ano ni‐substitute mo sa una, be consistent) You will get the y' Then susbtitute in the given equation y'‐y=2......if 2=2 Therefore, napili mo ang tamang answer..
30. Will be posted soon..... . . .
