Optimisation [IB Maths AI SL/HL]

[@kosogluefe]

This channel deserves much more. I’ve been doing the IB for a year now, and you’ve been a great mentor for me. Tons of love from Turkey❤️

Great to hear! Cheers, Mitch (writing from Denmark)

Hi Mitch, I have my exam tomorrow and your videos have been so helpful! I am so glad I found your videos, you make maths very fun (love your memes:-). I have already told my younger sister who is also doing the IB that she has to watch you videos. Wish you all the best!

Thanks, Selma And good luck this morning on Paper 2! :) Cheers, Mitch

hi Mitch, this is a really helpful video. I’m thinking of doing a math ia idea about optimising light. Is that mathematically possible? AHAHAHHJ I’m not sure how to calculate light or where to begin

[@OSC1990]

Thank you so much for the positive comment. As for your optimising light, you would need to be manipulating something specific about light itself and modelling it with an equation in order to optimise it. You can see the videos for Physics Topic 4 and Topic 9 to learn about light

wait so is the maximum value 1/2 or 0.5 ?

[@OSC1990]

Both would be acceptable on an exam :)

@@OSC1990 ah cool. Thank you!

hey, why would we graph V and not V'? thank you :)

[@OSC1990]

Depends what you're looking for. If you want to see where the max or min of a function itself is, then graphing V will show you that clearly (look for the local max or min). You COULD graph V', but then you need to be careful. The maximum or minimum will happen when V' is zero. So in a graph of V', you'd need to look for the ZEROS (ie where it crosses the x-axis)
