Modeling with Functions Part 1

We model real life scenarios of sales and volume of a box with functions. These type of PreCalculus questions will help to prepare for the sections of Calculus called Related Rates.

This man must know he is still helping people 10 years after.

You're welcome. I still find it amazing that I can teach students in the Philippines from a room in Florida:) Thanks for liking and choosing my channel to learn from! Please continue to share it with others and help make my channel the number one choice for free math help on YouTube in the Philippines:D

Have never seen a teacher as energetic as you

[Claypiqen]

You taught me in 15 minutes what my teacher couldn't in an hour.

Thank you soooo much! i'm a fourth year high school student in the Philippines and this video really helped me understand the topic =)

I have also started teaching after working for 29 yrs as an engineer. I am inspired by your way of solving problems and also keeping the viewers smiling. Great teaching !

[profrobbob]

That's great news...sometimes it just takes a different way of explaining:) Thanks for liking and I hope you come back for more!

[rosettejuico]

really helped me a lot..my modules frustrate me but thanks to you sir..i can understand everything now 😊🤓👍

Professor RobBob, thank you for a great video /lecture on Mathematical Modeling with Functions Part I. Applied Mathematics starts with these kinds of math problems.

[sheikhmahmud]

Nicely demonstrated. Now I am definitely motivated to relearn functions.

( theses videos r 10 yrs old )

started watching in 2023. Amazing lectures and very helpful. Thnxs a lot !

Using this video to recap some modeling before my first exam this evening. Let's hope it helps. I'm going to watch this and then hit the tutoring center for an hour and a half to go over the review sheet.

Word problems are challenging for me. But Mr. Profrobbob explains and illustrates so wonderful!
I love it!

[lawi]

Thank you sooo much !! im from saudi arabia and i've been taking calculus for business and the modeling and optimization part is just killing me
this is soo helpful !

[fourleafpoker]

I've been watching your videos since last semester. I'm just going to drop a little note of appreciation here. :) 

[pocketpin]

I wish I had teachers as enthusiastic with teaching as you are

[profrobbob]

@67lawi That is great to hear. Though I am only teaching PreCalculus at the moment, my new textbook seemed to have very similar problems to the Calculus book our school uses. I was really excited about that. So, I am glad to hear I am able to help Calculus students as well...and from Saudi Arabia! Very cool:)

[shawnthrizethah]

I feel like it's just the same as going to school while I'm am actually at home thanks to you sir! 😊

[daytimeempire]

Mr. Tarrou, you are the shit! My man! Keep making these videos. You are literally the only guy on youtube that I watch math tutorials from algebra to calculus. Try to go advanced as you can, like up to calculus 2. I'm in precalc this semester at the moment. Keep it up good sir. You are currently the math king on YouTube! :D
