Hello everybody. Thank you for visiting my channel.
The videos uploaded on this channel are usually for my students, so oftentimes, I am actually speaking in Tagalog or Ilocano.
I am happy that in one way or another, I may help other students out there who are eager to learn.
Please accept my apologies for some of my videos have unclear audio because I only use cheap headsets for my recordings. Haha. Anyway, if you want to connect, please email me at enggmathem@gmail.com.

how did u get from -20.31cos -35sin = 0 to tan
Plz tell me that how you take 100cm and 1m in this problem?
Sir pa'no po kung yung shift tan ganito: -CD/-CL = -(+0.27) / -(-1.02) Lahat po ba yan magiging negative yung sign? Or yung -(-1.02) magiging pasitive kapag nilagay na sa shift tan?
Hi
Sir, accurate ba ang survey kapag tape measure with gps (not sure Kung gps nga ba) ang gamit? Walang kahit anong equipment
thank you po. gamit na gamit ko sa review for board exam to. serve as refresher for me
how to input that in the calculator ?
Do you mean the angle?
Thank youu, napakalaking tulong neto boss sakto sa quiz namin
sir I thought if you get a positive error then the correction is negative.
how is 1/2 ( X + 8 ) equal to 1/2x + 4
1/2(x+8) - we distribute (multiply) 1/2 to each term inside the parenthesis = 1/2*x + 1/2*8 = 1/2*x + 4
nice video👍
Bakit nyo po kinuha yung angle theta? Di nyo lang nagamit
Very good explanation
(1±e/L) this formula is much easy than that. In my opinion.
Umakwana zakanembo. Apa waphweketsa ngini
BSCE1-D LEZZGAWWW
HI PU FROM BSCE-1A!
Sir, how do i determine if its left or right ?
hello bro!
Good day sir, should be the distance and adjusted length be equal?
Why did you measure the angles with a whole circle bearing and not just measure the interior angles to the right? Was there some advantage in doing it that way?
❤
hindi ba pwede na 0.03 yung sa last sir?
Confusing, why do you switch to your language whenever you wish? You make it inaccessible to others
should put this as NON-ENGLISH . BIG waste of time, do not watch this
Hello po. how about using the formula (0.204W√AE)/(Pn-Ps). will it still be the same? the formula I provided is a trial and error one. So I'm asking if using that formula (the one you used) will be easier?
hoy, HAHAHHAHAHHAHAHAHAHAHA
@@marilynq.batomalaque3587 Naga libog ko piste HAHAHAHAHAHAHAHAHHAA NAA MAN DIAY DALI DRE PERO DLI SURE IF PWEDE GAMITON 😭😭😭
sir, tanong lang po. what is azimuth from the south? will the distance be negative?
Salamat sa upload boss Jonas 😊
Hi sir ask ko lang po may pdf po kayo ng mga problems na ginagamit nyo, Salamat po!
Sir paano nyo inassume yung directions sa bearing of the side of error?
galing magturo, thank you po sir. gets ko po agad kasi sobrang detailed mo po magturo
Super helpful
Sir Halimbawa Po Equation 1 Ko p + d + q = 0 & Equation 3 d - 2d = 0 Paano Po Input Nyan?
Hello po mmsu stedent rin po XD
Hiii, ano po kaya yung minimum ng vent line thank you
sir yung bearing po ng LEC saan minimeasure? doon po ba sa dulong station or sa pinakaunang station
You are my favorite sir ❤
Thanks much buddy, you've made it simple for me
why do you switch to your language whenever you wish? You make it inaccessible to others.
ano po pinagkaiba ng distance between the supports and ng true distance
Hiii po, sana po magawak nyo yung combined corrections
Magawan*
thanks man. i have an Finite Element axam tomorrow and that was really helpfull. god bless you
help solve for x is always equals to zero. im using 991ES/Plus 2nd ed
Thanks for Video
If you're measuring and the tape is too short, wouldn't you add to correct the measurement?
good evening po..bakit wala pong section 30 to 39? thank you
Sa mga naguguluhan, if line is only due east, ibig sabihin ang bearing nya is parang N 90° E or S 90° E, therefore if you compute with the same formula, use cos(90) and sin (90) pero ginawa ni sir is understood naman na walang latitude or 0 latitude ang line na going east lng ang direction, and also na ang departure is same value nung line na going east.
sir pano po naging 52°13' pano po e convert?😭
Kapag po gumamit ng calculator ang lalabas ay 52.22431569° Tapos ang order po para maging katulad ng 52°13' is Degree Minutes then Seconds Yung magiging degree po ay yung whole number. Tapos pedeng 52.22431569-52=0.224315695 Tapos Yan pong decimal na iyan ay times 60 lang. Tapos ang lumabas ay 13.45894164 So ang for minutes is 13. And if you want to know what is for seconds, just minus 13 from what you get on the calculator. 13.45894164-13=0.45894164. Then times it again to 60. Tapos ang lalabas is 27.53649856 So kaya naging 52°13'
