You should teach mathematics, if not every subject, to every student across all classes through out the globe. The more I see your instructions the more I realize what rubbish had been taught to us. You are doing a stupendous job @ Salman
A population grows exponentially with growth constant 2. The emigration rate (as a function of time) is t 2. The initial population has size 20000. What will the population be at time t in the future?
e raised to the power of a constant is just a constant. For example e^3=20.083. So, e^c is a constant which can therefore be rewritten as just c (which represents a constant number) to make things simpler.
Because the ll operator means that the quantity inside it can be both negative and positive and the brackets smooth out that variation and give only a positive value. But population is a quantity that only has positive values. And so the ll operator isn't necessary.
Thanks for the videos, however i find it really annoying that you repeat and emphasise unnecessarily. It comes across condescending. We are learning math not english
I did this in school as a kid, chemistry kinetics class - never understood it - until now! and I'm 53 years old now, amazing!!

@@trashcan7140 Maybe he meant by Kid "22 years old" :D
Happy 60th birthday

Appreciate the great care taken in your teaching, until keeping the colors of the variables in the eqn. Tnx!
If you can not explain it simply. you don't understand it well enough. (A. Einstein)
But Sal Khan can it.
***** Sal Khan is the founder of khanacademy.org and he has the abiltiy to explain math stuff in a simple good way..
Right Sal Khan can it
The guy who is talking is Khan?
@@elchinitofeliz1699 yes
@@ifonlycainwereabel2110 im glad sal khan can it.

Thank you so much for the video it helped alot... :)
I like how he confused people with insects
Thanks man this was very helpful
What is K?
cool !!!
very helpfull video.
I hope you're my math teacher
how can one determine when to keep the c on the proper side, example how come u kept the constant on the right side and not the left?
because he was going to solve for p.
you could put the C on the LHS, and then move it to the other side. but why do an extra step?
Ah Thanks i thought it was just keep it on the dependent side but thanks for clearing it up
Hi, how can I access the next lesson/ video dealing with example of modelling population
how is e^c become C????? pls answer i dont see any rules of e regarding that
e raised to the power of a constant is just a constant. For example e^3=20.083. So, e^c is a constant which can therefore be rewritten as just c (which represents a constant number) to make things simpler.
You are so silly. How come you cannot guess that?? Even though he says that...
not everybody are even like you son
i got confused by this one too ataberk is rude.
@@djataberk1 part of the reason I didn't guess that is because I am used to solving for c then substituting it back in.
and the constant c is the population at time=0
But why is it modeling without a double ll ? :O
Because the ll operator means that the quantity inside it can be both negative and positive and the brackets smooth out that variation and give only a positive value. But population is a quantity that only has positive values. And so the ll operator isn't necessary.
