- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with:
+close
- Feel free to nominate the person for helper of the week in #helper-nominations
- Do not ping the mods, unless someone is breaking the rules.
- If you're happy with the help you got here, and the server overall, you can contribute financially as well:
Hmmm know the syllabus. Like what kinds of topics covered?
If you learn quadratics, that would do
see how familiar you are with these terms:
vertex
vertex is the middle of the roots
roots
ax^2+bx+c form
a(x-k)+h form
completing the square
quadratic formula
@jovial linden ^
also if you know three of the points on the parabola you can solve for a b and c with systems of equations
This is very interesting and we have not learnt thing
yea that’s taught less frequently which is tragic
that would be second order lagrange interpolation actually
You have to be familiar with roots, the quadratic formula (if you have problem remembering it there is a way), the sum of roots, multiplication of roots, the formula x^2 - (sum of roots)x + product of roots = 0 and maybe even the middle term split.
These are what I learned and I aced my Quadratic exam.
