How to Find Limits by Direct Substitution?
How to find limit by direct substitution. In this video, we will go through some examples in finding the limit at a point of a function by using direct substitution. However, direct substitution cannot be used to find the limit if we end up with 0/0, which is an indeterminate form. Instead, conjugate method must be used in this case.

What is the derivative of e^2x? As e^2x is a composite function, we will be using the chain rule to find its derivative. For taking the derivative of an exponential function using the chain rule, we just have to copy back the exact same thing as our original function, then multiply it by the derivative of its exponent. In this case, we get 2e^2x as our final answer. #derivatives #differentiatio...

Quickest Way for Limit at Infinity WITHOUT Dividing Every Terms
Thanks for making this, these videos really do help people out!!
I'm preparing for my exams, and I wanted to give praise to your explanation. You presented this topic in a very clear and intuitive way for people to understand. Very well!
What if it is e^x(x²)dx Do i set u to x² And dv to e^xdx
I have a question
Anyway thnkx so I got problem why u conjugate numerator instead of conjugating denominator x
It depends on situations. We actually want to get rid of the square root, so we multiply the fraction by the conjugate of the expression that has a square root. For example, if the square root is in the numerator, we multiply it by the conjugate of numerator instead of denominator.
Thank u
No problem
How about integrating "sin 2x"?
sad this wasn't a fish to the fish video :(
Your animations are amazing How do you make them?

please make more videos on integration
I love this!

Amazing explaination broo👏👏 Please keep making these videos they are very helpful
Thanks! I'll try my best
How you make this animations?

This is the first video on CZcams that am commenting on, but woow, your explanation is on another level. Thanks please, much appreciated.
Glad to hear that!
next video -> why d(e^x) = e^x*dx
... The 2nd indeterminate limit can also be solved as follows ... in this case rewriting the numerator x - 5 as (4 + x) - 9 , and considering this expression as a difference of 2 squares ... (4+ x) - 9 = (SQRT(4 + x) - 3)(SQRT(4 + x) + 3) ... then cancelling common factor SQRT(4 + x) - 3 between top and bottom, giving us a solvable limit form in return ... lim(x->5)[SQRT(4 + x) + 3] = 6 ... solving this limit by factoring and cancelling ... thank you for your clear and instructive presentations ... take good care, Jan-W
❤❤
... Good day to you, Another way of solving your indeterminate limit, is to rewrite the denominator x in its original form as follows ... x = (4 + x) - 4 , and then treating this expression as a difference of 2 squares ... (SQRT(4 + x) - 2)(SQRT(4 + x) + 2) to finally cancelling the common factor (SQRT(4 + x) - 2) between numerator and denominator, to be left with a solvable limit form ... lim(x->0)[1/(SQRT(4 + x) + 2) = 1/4 ... solving by factoring I think I would call this ... thanks for sharing your instructive math channel with us, the interested viewers ... best wishes, Jan-W
Excellent explanation
Thanks!
Very great work, perfect explanation
Glad to hear that! I appreciate it!
Don't know how much you have to pay for AI voice, but you should consider switching even if you have to pay a bit more. Get an AI voice that knows a little math. "ln" is not "lawn" as in "mow the lawn". Once or twice might be charming but the whole video is about ln so "lawn" gets quickly annoying. Mike
That is how it is pronounced
God bless you
Thank you
No worries!
You don’t need to say it’s lnx times 1 lol just let dv = dx
You're right! I was just intended to provide a better clarification and understanding.
@@YeahMathIsBoring right I know but I don’t think it does
dv is just the rest of what’s left over
Since IBP is taught as a method for integrating products of functions is good to mention it at least though
@@coreymonsta7505 Yup, cuz some might think that lnx is just a single logarithmic term and they're confused why IBP is applied here
In the case of a pure inverse function, the integration by parts formula can be derived from the graph: int x dy=x*y-int y dx
1:07 Why all that talk 🤣 we know that eⁿ = x remplace it
Use first principles.
You kids get off my lawnx!
Can this be a method to prove the f'?
Absolutely! You can prove the derivative of f(x), which is denoted as f'(x) using the first principle of derivatives. In fact, first principle is the actual definition of differentiation, and the power rule that we normally use is actually derived from this formula.
Hard matn😅
but if we look at x^3, wouldn't y= x+1 be a tangent to x^3 at x = 3 be x+24? The slope of x + 24 is 1 but with differentiation, slope of tangent = 2*3^2 = 2*9 = 18?
If a line intersects the curve at only one point but does not have the same slope as the curve at that point, it is not a tangent line. It would simply be a line intersecting the curve at that point. The key aspect of a tangent line is that it is aligned with the curve's slope at the point of contact. I totally agree with you where by using differentiation, even with the first principle, we get our gradient function as 2x^2. If x=3, then 2(3)^2 would be 18, meaning that the gradient of the tangent line is 18 when x equals 3.
Thanks for making me understand more about this topic. I would like to ask does chain rule applied to all implicit equations? And if not, in what situation we can use it?
Yes it does! To clarify, chain rule is applied the on terms that have composition of functions, in which we differentiate the outer function without changing the inner function, and we then multiply it by the derivative of the inner function.
@YeahMathIsBoring would like to clarify more about on terms?
@@aziqasri5435 For example: (2x-1)^2, this term can be said that it has a composition of functions. But how? We let f(x) = x^2, and g(x) = 2x -1. When we plug in g(x) into f(x), which is denoted by f(g(x)), it would be (2x-1)^2. Notice that it is exactly the same as the original term. Therefore, we can say that f(g(x)) is a composite function, and that's why (2x-1)^2 can be said that it is a term that has a composition of functions. You may check out the video I uploaded to learn more about this in the chain rule topic: czcams.com/video/js8jOoWyZ2M/video.html
@YeahMathIsBoring thanks again, good sir. Anyway, I have subscribed to you.
@@aziqasri5435 Glad to hear that! I appreciate it!
"lawn y"
Can we take the derivative using power rule by applying dy/dx=sin x *sin x?
You can use product rule as y = sin x * sin x
Very comprehensive explanation
Thanks!
to the point explanation very great.
Glad to hear that! I've put everything I have into this explanation video.
Quotient rule...
Also from cos^2(x)+sin^2(x)/cos^2(x) we get 1+tan^2(x) which is by identity of sec^2(x)-tan^(x)=1, we have sec^2(x).
Amazing , just keep on posting more stuff
Thanks! I will try my best
Can this be done by implicit differentiation?
It's indeed possible actually. You'll first have to apply natural logarithmic on both sides of the equation.
Tq sir ❤...
