I dont think ill get a 6, but lets hope for the best! if i do get it, its because of you Mrs. Juliana!

[fguizini]

Juliana, o que seriam as siglas "courses AA and AI, SL and HL"?

[yagmurserin]

hi, i want to thank you. this video is very helpful and you are very beautiful and smart
!

super cool video, i love the way you explain things! helped a lot! was just wondering, for the example taken using the third method, why couldn't homogeneous equations be used? you mentioned its because the other variable had a log but it was in terms of x so im not sure why it still couldn't be used

[jandirpassos]

Very usefull lesson. I hint you show more differential equation applied in physics.
