Dear All,
I am having issues understanding the video and the interactive tool, in both cases I cannot understand how the numbers are being calculated.
The instructor says let’s imagine the following is 750t^2
Thank you,
David
From what I understand the 750t2 is an approximation here, he is saying lets imagine this function is approximated by that.
The second one should be a different graph from the first one.
Hello there, thanks for the reply.
I noticed that he said let’s imagine (or an expression similar to this one) but I don’t get it and I cannot fully understand like this. I know the point is not this but how it affects the first and second derivatives but still I would like to understand.
Same goes for the second example, I know it’s different but still I don’t get it how the 5t^2 or right after, 20t-20 is coming to the picture.
I haven’t done this course but I believe that he explains how to calculate derivatives, but if he doesn’t then you need to find a source to understand how you calculate derivatives and integrals…for example the derivative of 5t^2 is 20t!
