I have my final tomorrow. I thought i hated stats then you make me fall in love with it now. You are a blessing. Thanks, your video makes me understand
I found myself reviewing this material 2 days before my exam. Fighting
I've finally understood it. Thank you!
Where did 2/-2 come from?
Watching it for the first times still blank abit watching over till i get it in my thick rock hard brain
these kinds of concepts require a big deal of concentration and practice not only watching someone explaining it either on The Internet or at university(from experience).
Tnx alot sir.
Using the power rule, 2/(x+1)^3 should equal -6(1/x+1)^4 right? Because you'd take the -3 exponent out front and subtract 1 from it, making it -4 since it's a fraction. Then with -3 out front that'd give you -6 from multiplying by 2. That's where my only confusion comes from. If you could clear that up that'd be great because I'm sure I'm just missing something.
He is using the power rule for integrals which says the indefinite integral of x^n = (x^(n+1))/(n+1) [so the indefinite integral of 2(x+1)^(-3) would be 2((x+1)^(-2))/(-2)]. You were doing the power rule for derivatives.
Jon Atkins That clears it up! Thank you.
although the concepts told are correct and the flow too is awesome but the graph you've drawn in CDF example is incorrect , PLS see to it
I assume you talking about ua-cam.com/video/PQ7oELoDIPY/v-deo.html ?
F=1-(1/(x+1)^2) for positive x ... The graph is correct for this function.
Are u sure u are in the right place?
wow
thank you so much for this subject .I will be very grateful if you send me your email I have some questions and want you to answer them
