god bless you

Less than 10 hours to exams, im cooked😭 By far the best explanation on RUclips

If you can't understand what she's doing, you have a lack in your matrix knowledge. Try whit an easyer argument

Woman/ Prof/ Lady you are the best

You saved my life thank you

Wow you got tha brains and the beauty😎 but still doesn’t answer my question what’s u +me =?🧐

I used this video during my undergraduate and I’m using it during my masters rn, recommended it to my friends and it’s the best(concise and understandable) video on simplex method out there. Good job, ma’am.❤️

i have question if in the same line have more than two variables have 1 and number in the last line greater than 0 what can I do Note :I have example for this.

Barikiwa sana. (be blessed)

God this was so helpful for me. Thank you so much

Wow you taught it like a peice of cake!

What to do in a situation where step 1 after division are the same vaues

Thank you.💐 you helped me a lot

thank you, i u derstand it now even im not good at english but your explanation is easy to understand

Thanks a ton really helpful

I love this, but is there any way to do this WITHOUT a calculator? I’m in precalculus and we’re not allowed to have one… I’m struggling

thank you dr d!

I'm really appreciate you , you're content is very helpful

9 years later and you are still a life saver madam

the values of ranges of constraints are not correct. Excel shows the correct values. While calculating the range of 'h' we also need to take into consideration the restrictions put by remaining constraints.

No pilot would be interested in this. This examples solves for where an airplane would go given wind speed and direction and aircraft heading and airspeed. But, the actual aircraft problem is to find the crab angle and ground speed given a desired ground track. That is, the aircraft problem is: given the departure point and desired arrival point which heading do I point the aircraft in, and what is the ground speed. This example merely shows where an aircraft would go given a aircraft heading and airspeed and a wind direction and speed. This example does not solve how do I get from fixed A and B given wind speed and direction and the fixed points. The problem can be solved using the law of sines twice rather than the law of cosines and is somewhat more complex than this irrelevant solution (?). Pilots are interested in how to get from A to B, not where the wind will blow them if they don't make any sort of crab angle correction.

Does the "simplex method" sound like a misnome to anyone?

This bring back memories from my Intro to Quantitative Methods One and Operations Research courses when I was a Business student at Saint Mary's University during the mid 1990s.

nice

Too fast don't understand 😢

My professor spent 1h30 minutes on a 7 minutes problem🤦‍♂️

Dr Math, can you please please solve a problem where one of our constraints is negative ont he right side? For example: Min 3x1+x2 Constraints: x1+x2<=5 2x1+x2>=8 x1,x2>=0 Please if anyone can solve this!

Question: Before reading through the entire question, how can you assume that there are only 2 types of drinks (A and B)? What if there were 3 types?

its important showing every step

With all due respect, some people do not know how to teach but that lady definitely knows. Straight to the point with the application, no confusions and very clear

Watching it 9hrs before exam. Wish me luck

Wow😍

Can you solve this with min? and where we have >= in some parts instead of <=?

Is this how you will teach yourself when no idea about it

it is working, nut i have no idea how it works

clearest explanation in nearly 8 minutes! thanks!

No clear ... to long steps betwee😮n ... be carefull ... I'm trying normal teach ...

Dr D, you are a real treasure!

the thing i m gonna say may not be relative to the course. ur voice is close to my grandma, it s soft and warm, i never thought i can hear it on youtube. thanks

Amazing!

I learned more about how to do this method in 7 minutes and 43 seconds than I did in an hour of hand-wavy lectures. Thank you very much.

,would you help me some questions?

how did you get 31.1795?

Great Explanation !!

You ma’am, have just earned yourself a subscription

Got a question, what if one of the contraisnt doesnt have an x1 or x2

God bless

Ma you’re just too smart and plain,I give you your flowers 😁

This was very helpful. Thank you!
