Vieta's Formulae: STEP I roots of polynomials
Why is it when you multiply the diagnols of a rhombus and divide by 2 that equals the area
If the diagonals are of length 2a and 2b, then the side lengths of the triangles (quarter-rhombi) are a and b (because diagonals of a rhombus are perpendicular bisectors of each other). Thus, the area of one of those triangles, 1/4 * Area, is equal to ab/2. This means that Area = 4 * ab/2 = 2ab = 2a * 2b / 2.
@@FunMaths15 thats amazing thank you!
Oh my Euler ... this channel is indeed about Mathematics ...
Nice video! You concisely explain the solution. +1 sub from me
Great video. Really enjoyed it. You include just enough detail that if I think about it I can understand each of the steps. Most of the maths videos that I watch have too much spoon feeding. Yours doesn't. Thankyou
unusually easy STEP question... some usually slip the net
1:50, I got an answer of x = 5 - 3/2 sqrt(11) for the first question...I cannot figure it out how you got discriminant equal to 42...sorry
Hi @Dragon95161, The discriminant for the quadratic in y is 6^2 - 4 x (-1) x 2 = 36 - -8 = 42. You just need to be careful with negative signs - I know I always have issues with those!
@@FunMaths15 I just realised, 36 + 8 = 44!
Great Video, I didn't though I would find any video for that topic but you answered all my questions! ❤❤ Thanks
Thanks for the support!
there is a problem with your channel
This is really fun and interesting, I love it!
Yay, thank you!
