Since this is an introduction that spans the entirety of the Stack Exchange network, I would just like to say... I love them all!

How can I introduce complex numbers to precalculus students? I always imagine complex numbers as a plane, only with one axis as the imaginary numbers. I thought it was the only way to do it, really! |

Number of points at which a tangent touches a curve @RobertIsrael - He said it exactly like I said. Maybe he didn't want me to get into detail - I'll give him benefit of doubt since he was at the end correct. Plus, he is otherwise an excelent teacher! |

Number of points at which a tangent touches a curve This seems intriguing, and though I don't understand bits of it right now, I would have just have to study more. Thanks for your answer. I was expecting something of this kind from this site. :-) |

What are the points of discontinuity of $\tan x$? So you are saying any discreet function is continuous? That is logical if one comes to think about it. Plus, I am sorry I couldn't get the part of essential discontinuity. What does the notation D-dash mean? |

What are the points of discontinuity of $\tan x$? Actually, the definition in any textbook I referred to give the definition of points of continuity only. They are dead silent when talking about discontinuity, whether f(c) needs to be defined or not adding to the confusion. |

What are the points of discontinuity of $\tan x$? I read about the extended real line in calculus as $\mathbb R \bigcup \infty$. That is, they treat $\infty$ and $-\infty$ as the same. How can they be same? There is at least a minus sign as a point of difference between the two. Wikipedia on compactification asks to treat real line as a circle where its open ends meet at $\infty$. Yet real line is infinite in length! Do we treat the radius of this circle to be infinite too? Isn't it just more practical to add two points, $+\infty$ and $-\infty$ to real line, and more intuitive too? |
