IB Sample Exam Q10, Paper 1

This video is the last video for paper 1 of the Sample IB exam.
In this video, you have to derive a formula to show the amount of time a farmer takes to cross a field and reach another point. After finding the formula, you then have to find where he should travel to along a road in order to minimize his time. You must justify this using calculus.

This kind of devotion to teaching and learning deserves a tidy sum. You're an inspiration to us all Patrick.

@@patrickjmt you will make lots of money one day. You should do private tutoring to help people, I know lots of people will pay good money to have you help them understand mathematics.

Very good

[@AliHSyed]

But why did the farmer cross the field. Was he happy with his life? These are most important questions.

A decade later. My man PatrickJMT!! I’m an electrical engineer today, thanks for the help along the way Patrick!! 🙏🏽

5 Years later, I've graduated as an Electrical/Electronics Engineer, best in my faculty, with a CGPA of 4.76 on a 5-point scale. Thank you so much, Patrick. We are grateful.

[@patrickjmt]

congrats man, that is awesome!

[@MrKrewie]

6 years later and i graduated as an engineer, had a pretty hard time with math but your videos definitely helped me overcome my shortcomings, thank you Patrick and keep up the good work! 🙏

Wow this video just popped up to me and I still remember that I learnt math through your channel and graduated as an engineer 4 years ago . The only difference now and then is that you are now using an iPad lol .. in my times it was real papers and pen. Well done sir

[@quant-prep2843]

please make videos on linear algebra....
nobody ever truly explained linear algebra in youtube.

[@madnecessity]
