Can you cross a slant asymptote?
Space and AstronomyA graph CAN cross slant and horizontal asymptotes (sometimes more than once). It’s those vertical asymptote critters that a graph cannot cross. This is because these are the bad spots in the domain. Can a function intersect with a slant asymptote? Graphing this should be self-explanatory. With horizontal and slant asymptotes, the function itself can

What if there were no mirrors?
Space and AstronomyThe focus of our society would shift to a more fundamental, personality driven motive. “Without mirrors or reflections, people would have a chance to feel more comfortable about what they look like because they wouldn’t have to worry about fixing things about themselves until they’re perfect,” Gillman said. What was life like before mirrors? Before

What is the multiplication rule for independent events?
Space and AstronomyThe specific multiplication rule, P(A and B) = P(A) * P(B), is only valid if the two events are independent. In other words, it only works if one event does not change the probability of the other event. What is the rule for independent events? Events A and B are independent if the equation P(A∩B)

How does the Gregorian telescope work?
Space and AstronomyThe Gregorian telescope consists of two concave mirrors: the primary mirror (a concave paraboloid) collects the light and brings it to a focus before the secondary mirror (a concave ellipsoid), where it is reflected back through a hole in the centre of the primary, and thence out the bottom end of the instrument, where …
