What is a parabolic line?
What is a parabolic line?
In differential geometry, a smooth surface in three dimensions has a parabolic point when the Gaussian curvature is zero. Typically such points lie on a curve called the parabolic line which separates the surface into regions of positive and negative Gaussian curvature.
What is the difference between a parabola and a line?
A line can meet a parabola in at most two points. If the discriminant of the resulting quadratic is negative, the line does not meet the parabola at all. If the discriminant of the resulting quadratic is positive, the line meets the parabola in two distinct points.
How do you describe a parabola?
The graph of a quadratic function is a U-shaped curve called a parabola. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.
WHAT IS A in parabola?
The general form of a quadratic is “y = ax2 + bx + c”. For graphing, the leading coefficient “a” indicates how “fat” or how “skinny” the parabola will be. Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the “vertex”.
How do you find the equation of a parabola in a banana?
Now, we know that a parabolic shape must have a quadratic function, therefore an equation in standard form of f(x)=ax2+bx+c. To find an equation for the parabolic shape of the banana, we need to find the values of a, b, and c. We can do this by using a slider in Geogebra, and name them a, b, and c.
What are some real life examples of ellipses?
Many real-world situations can be represented by ellipses, including orbits of planets, satellites, moons and comets, and shapes of boat keels, rudders, and some airplane wings. A medical device called a lithotripter uses elliptical reflectors to break up kidney stones by generating sound waves.

What does God say about a rainbow?
Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth.” So God said to Noah, “This is the sign of the covenant I have established between me and all life on the earth.”
