This exact problem was on my calculus test and I didn’t know what to do so I just skipped it, thanks for your help for the future though 😂

I've been watching so many videos trying to understand this concept and this specific question and your video finally gave me the "Aha!" moment I was looking for. On top of that, you explained it very well under 5 minutes! Thank you so much

question: where is x=40 to be used?
@jtlbb2
@jtlbb2 6 месяцев назад
One of the things that makes this problem tricky is that his distance from the pole, 40 ft, never mattered. I solved this problem correctly but kept trying to go back and incorporate the 40 ft some how lol.

x=40ft not used ?

I was wondering that myself. Let's say we want to know the speed when he's 10 feet away; you would get the same answer? That has to be wrong because the angle's different.

why is the answer dy/dt+dx/dt

Isn’t it -5 since His walking away from the pole?
@MohammadJadallah-tp7nk
@MohammadJadallah-tp7nk 9 месяцев назад
Nope if he’s walking away from a point then it’s +value while if he’s walking toward a point in other word he’s getting closer to a point so it’s a -value

I just found dy/dt and i though that's the answer but now i understand why dx/dt+dy/dt is answer.
