excuse me, can I ask you something? at 3:40 why you type -b/2*a rather than -b/2/a ?
Thanks for your question. Yes, x = -b/(2a), thus the typing is -b/2*a
When there is only one root, the vertex is the sole intersection of the parabola with the x-axis. According to the vertex formula, the x-coordinate of the vertex is given by x= -b/(2a). Furthermore, by the quadratic equation, when the discriminant b^2 - 4ac = 0, we find that x = (-b +- sqrt(0))/(2a) = -b/(2a)
The solutions of a quadratic equation are known by several names, all of which are equivalent: root, zero, and x-intercept. Additionally, in graphing contexts, they can also be referred to as the intersection points of the parabola with the x-axis
Good k teach
Aha.. -ln(a) is included in the new C thank you
Thank you Jing! great help
Amazing video, to the point, without any nonsense. Liked and Subscribed!
Good🎉
Now can you do this without using dual axis chart?
Thank you! Good guide and explanation!
incredible!
nice
Thanks Jing!!! Really helpful! Made it easy cause I'm making an Apple Stocks dashboard for my Tableau Public profile.
谢谢你jing！对我的期末作业帮了大忙！
有用
Nice video dear.👍
difference between inclusive and exclusive quartile is that inclusive ignores the maximum value (in this case out of 10 it will only choose 9 values) and in both median will be same...
Thanks for the tutorial, that was realy useful.
Great video!
Very helpful, thank you!
Thank You
THank you so much helped a lot
Hi Jing, Thanks for posting it and I found it really useful. Can you please explain why you add 1 in the interval calculations.
this helped me a lot! Thank you
