Ingenious Method to Solve Killer Calculus Question from 2023 Korean SAT Math with @TomRocksMaths

In this video, I am presenting step-by-step solution to this extremely challenging question from 2023 Korean Suneung SAT math with @TomRocksMaths We used different methods, and I am introducing my method in this video. Please make sure to go check the YouTube channel of @TomRocksMaths and see how he approached this question and solved it. This question was a challenging calculus problem using trigonometric function and composite function, and this was what many of the students struggled to come up with the final answer. To be more specific, I used more of graphing method, and @TomRocksMaths focused on algebraic work to solve this question out. 2023 Korean SAT Suneung math exam was difficult. I am also planning to cover other questions, too. Make sure to watch this video until the end, and check @TomRocksMaths channel at:

Hello, guys. In this question, there is one missing word. h(x) has a "local" maximum value of 0 when x is 0.

This is by far the best collaboration Ive ever seen. Also checked Tom RocKs Maths

Awesome Dr PK. Love that your using the whiteboard. I solved using a similar method it and got f(x)=5/3(x^3/3-3x^2/2)+8 and f(2)=22/9, 22+9=#31, ,
Keep up the great work 👍 👏

Amazing work. what you worked on cubic function, the distance, was something I havent seen before. thanks for sharing

[mathnerd]

Very nice. please sir do more of these videos, you standing in front of board and doing the work. you look very professional

Amazing how Korean students have so tricky and interesting questions on their entrance exam, Brazilian exams are not at that level of greatness lol.
Greetings from Brazil 🇧🇷 and congratulations for the amazing work 🎉

Graphical methods usually require just the right amount of cleverness and that too at the right place. It doesn't require remembering or working out much formulae, or that's how I like to think. A nice problem indeed. Thank you. 🙇

Nicely done! My only critique might be that if I hadn't done the problem myself and thought about f(x) being related to the arcsin, I wouldn't have understood why you were counting things on the x-axis and saying that it meant f(0) = 8. At least TO ME, it seemed like you were saying something about x=8 meant something about f at x=0. But I enjoyed how you explained your process!! I went for a completely non-graphical solution. Rene Descartes is my friend, and I almost always move something living in graphical land to something that lives in algebra land.😊
