This is very informative. However, I wonder how to determine the domain of a function like this: f(x)=√((x+1)+√(x-1)) where the second square root is included in the first one.
I really like this series, but the smacking of the lips as the repetitive vocalized pause throws my thought process off. Just some feedback.
thumbs up for the controller!
Sir of lately I have become a fan of yours (currently doing the coursera course ) , rarely I have seen a happy face maths teacher , you are doing a great service to the society or for students in third world nations like India , I am sure this is the way to go for the future , kudos to you !!
How about the range though??
Kudos to you! 😉
Difference between pros and noobs is that noobs say "positive numbers and zero" while pros say "nonnegative numbers"
so in 8.25 you conclude that the domain of square root function only works with zero or positive number?
