Thank you!

hey this aint algebra

My brain is going to explode from watching this video...

@MrAimsworth Well, if you're learning about expo growth, most people use the equation A=Pe^rt in which e^rt is the exact same as e^kt. Both equations are the same, just with different variables. P is the initial amount, e is the natural log to the power of (r times t). r is the rate and t is the time. I hope I answered your question!

Hi Sal, I think you maybe should re-do this one, and start of by introducing the general formula for exponential growth y=a*b^t, (where b is the growth factor, a is the initial value) and then move on to how it's useful to manipulate this into an exponential function with base e.

I was a bit confused by this at first, and I see others in the comment section are too.

This is the exact same problem ( problem 3) i was looking at in my book, Early Transcendentals

I think he needs to give a more intuition on how e^ln4.2 works.

Better to say ln(x) is the "undo" function of e^x and vice versa.. ? So func(inversefunc(x)) = x

thank you so much! I was stuck with this.
