[@psalmlewingotera6451]

THANK YOU, watched the 2 videos about 4x4 cal tech. At first I got dimension error. Until, I found my error. Works well! I subscribed for you as I as a thank you.

Thank you!💛

The (1+4) I don't understand. Did you separate 14

[@EngineerProfPH]

Hello! The 1 and 4 means that the position of your pivot is in the 1st row, 4th column.

what if my pivot is 0?

May vid po kayo na 4x5? Matrix

[@pembotolentino7431]

Why dimensions error?

[@EngineerProfPH]

pls repeat the process sir. Clear your calcu first. shift-9-3. Then do exactly whats on the video. Always choose 1 as your pivot. 👍

What if 1 ( on (1,4)) is zero?

[@leobesa2887]

Row 1, column 4.

[@EngineerProfPH]

@@leobesa2887 HI! Dont choose zero. if there is no number 1, just pick any number like if you choose 2 as your pivot, multiply all the numbers in your matrix by 1/2 to make it 1.

Podria alguien explicar lo del -1

[@maryson5078]

Starts at 1:53

[@traveherofilms7781]

Saan galing yung (-1)^(1+4)

[@EngineerProfPH]

1 and 4 is the position of the pivot. 1st row 4th column:)

[@parkhello2262]

eh yung base na (-1)

[@EngineerProfPH]

@@parkhello2262 If you solve this using the pivotal method, -1 is actually a constant in the formula. It is concerned with your change of sign (positive or negative), so its really important.

[@EngineerProfPH]

@@parkhello2262 I will be uploading a revised video for this. :)

[@EngineerProfPH]

If you use the pivotal method, it is in the formula. It deals with the sign of your determinant. It also depends on the position of your pivot.
