Hi. 4m is the height of the water level. The problem requires us to solve for how fast the water is rising at 4 m water level. Thank you for supporting this channel!💛
Sir bkit di pwede na gamitin agad yung formula ng V = d / t, solvable si time given ang V1 and S1, then solve na for velocity when S=50, velocity will be 18ft per second. Too convinient pero mali sir? Bakit po kaya
Hi! Nagkataon lang po na yung ganitong alternate solution ninyo ay fit sa problem. If you look at it po, you are actually using a derived equation from dynamics (which is galing lng din naman po sa calculus). Thank you!❤️
Hi po! Ginamit natin ang 6/12 para makuha yung relationship ng height with respect to radius in general. Yung 4m po sa derived equation na po yung i substitute since ang question is how fast the water level is rising when the water level is 4m.
Hello po! Sa first question nyo po, divide lng po sa 2 both sides kaya po nasimplify. Yung sa 2nd question nyo po, same lng din po, simplify lng po using algebra. Thank you po!
@@JoshuaDetablan bakit kelangan idivide sa 2S? saka bakit hindi na multiply and 225 sa 2t? as per principle dapat imultiply ang 225 sa 2t. Please see this ruclips.net/video/U8cAVqkBBso/видео.html at 3:21
Yes po, you can multiply it by 2 but in this case no need na kasi magcancel na yung 2 both sides upon division. Then you extract, ds/dt to get 225/s. Thank you for your question. God bless!
The sides of a triangle measuring 40 m, 32 m, and 16 m increase at the rates of 2 m/s, 5 m/s and 3 m/s, respectively. How fast is the area of the triangle changing? Ask ko lang po paano process dito
Whoa!ganda po ng pinapakita nyo mona yung concepts tapos calculator technique,tnx..
Salamat po! God bless💛
Sana pagpalain kapa ng panginoon. Salamat ng marami po
Thank you po! God bless❤️❤️❤️
Thankyou siiiir. Such a great help 😭💖
Thank you for your support to this channel!💛
What's the differences of Time rates and rate of change?
Sir may tanong lang ako, doon sa 1st question, saan po galing yung 4 na height?

4meter deep diba bakit 6 over 12 ?

May cal tech din po ba sa prob 2?
hello. sa second question po 10:33, bakit po nawala ung 30^2 sa equation?
Derivative po ng constant is zero
@@rahleigh5829 thank uu
thank you po sa calcutech
Pano po naging 50 sa 12:04
Hi! Sq. rt of 30^2 + [15(2.67)]^2 = sq. rt of 900 + 1600 = sq. rt of 2500 = 50
sir ask lng sna ako @ 10:30 s video, bkit po naging ds/dt =225t nlng? at sa @4:33 s video bkit po naging 4(8)/pi2(h) dh/dt po sir.?
Hello po! Sa first question nyo po, divide lng po sa 2 both sides kaya po nasimplify. Yung sa 2nd question nyo po, same lng din po, simplify lng po using algebra. Thank you po!
Sir bakit po naging s1 sa second question diba meron na pong given na 15ft/sec?
Sir pano po naging pi/12 (3h^2) (3:27)
pi/12 is constant and 3h^2 is the derivative of h^3
sir bakit po naging 50 yung s? (12:04)
Yung sa may square root of 30^2 + [15(2.67)]^2 po☺️
@@EngineerProfPH ty po
sir bakit yung other formula may pay (π) pero yung iba ayh wala
sa second question, paano naging 225T/S? Please check 10:33.
Divide both sides by 2s, so ma cancel ang 2 sa 225(2t) kaya 225t/s nalang
@@JoshuaDetablan bakit kelangan idivide sa 2S? saka bakit hindi na multiply and 225 sa 2t? as per principle dapat imultiply ang 225 sa 2t. Please see this ruclips.net/video/U8cAVqkBBso/видео.html at 3:21

Engineer, sa number 2,dba sabi 40 ang ballon from point a?
Ang tanong: Saan nagmula ang ballon? Sa point A? or sa point B?
paano naging R is equal to H all over 2? Please check 2:10
Cross multiply po then divide 2 to get r
@@JoshuaDetablan gets ko na to by triangle formula
Hi Sir sa second Problem bat mo naging 50 yung sagot 31 namn po nung nag calcue ako huhuhi
Hi! Sq. rt of 30^2 + [15(2.67)]^2 = sq. rt of 900 + 1600 = sq. rt of 2500 = 50

I specify mo ang parts kung saan jan ang height, base at sides
san po galing yung 1/3?
sa 1:20
ahm hello po sir ask ko lang po saan po nakuha yung 40 (10:51)
given po
all over
hahah pasensya na po sa accent ko 😂
@@EngineerProfPH ok nga boss eh, mas madali ko naaral yung lesson. madali matandaan pati.
