Engineering Riddle – No. 1 (Math) “I may cross once, I may cross twice…”
I may cross once, I may cross twice, I may cross never, but never thrice.
When starting up, I finish down, I finish up, when starting down.
I have three parts, some friends would say, One straight, one curved, one same all day.
With time and place and rate of flight, I’ll tell you where you’ll be tonight.
And when you throw a ball up high, I’ll tell you when to close your eye.
I’ll use my shape to bend the light, And take you close to stars at night,
And if you want to talk to friends, Transmit/Receive, I’m on both ends.
Now if my name you still can’t state, Just draw a line, then integrate.
What am I?
Parabola was my guess as well, but that is incorrect based on the above response. How about “quadratic function?” That seems to satisfy the “one straight, one curved, one same all day” criteria with the three components of the function.
Quadratic function is the correct answer. Parabola, Quadratic Equation, and Quadratic Formula are unique. Quadratic Function is f(x) = ax^2 + bx + c. Good job John.
parabola
Parabola is an excellent answer, however it does not satisfy all the criteria. What is a parabola a subset of?
parbola?
