To find the y-intercept, set x to 0 and solve for y. y = 2(0)² –4(0) + 1 y = 1 This makes the y-intercept point is (0,1). 7 Components of a Parabola From the focal point to the fixed, straight line of the directrix, these are the parabola components that define...

As Dr. Li explained to Universe Today via email: "The main advantage of FAST is its effective collecting area. FAST forms a parabola of 3000-meter diameter, and a total collecting area in the L-band (coveringneutral hydrogen, etc.), which is larger than those of any other telescopes, in...
Suddenly I noticed a hex nut on a piece of equipment. The lightbulb went off. I slapped my forehead and said Duh! Hex nuts are hexagons. They come in an amazing variety of sizes. They are easy to find and relatively cheap. I went online and found a table showing the dimensions of ...

We can even apply this idea to conic sections, letting an ellipse send off one of its foci to infinity, becoming a parabola for a split second, and thencoming out the other side, twisted in the process, to reveal a hyperbola. So much of math revealsbizarre and beautifulnew worlds when ...
Using the Correct Formula to Find the Focus of a Parabola If you’ve ever cooked food with a parabolic oven in science class or seen the Death Star’s laser in ''Star Wars'', you have an idea of what the focal point (or focus) of a parabola is. But how do you calculate the fo...
