    • @JonasClassNotes
      @JonasClassNotes Před 2 měsíci

      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

    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?

  • @jbonceu2457
    @jbonceu2457 Před rokem

    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.

    • @Watchermelon0725
      @Watchermelon0725 Před 3 měsíci

      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'
