mom, our teacher was teaching us math today, and i was thinking how useless of a subject it is.
because when are we ever going to use it? i get simple addition and multiplication, but she said we have to learn para-par-...........ebola?
yeah, its called parabola. The name sounds so scary that i dont want to grow up or study it
a parabola is a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity follows a curve of this shape.
The vertex form of a parabola's equation is generally expressed as: y = a(x-h)2+k. (h,k) is the vertex as you can see in the picture below. If a is positive then theparabola opens upwards like a regular "U".
even that opening of a tree gives us an example of a parabola
so i hope you learnt a little more about what a parabola is, the further you advance the more you'll know.
