How to prove that $\lim\limits_{x\to0}\frac{\sin x}x=1$? @CutieKrait We defined $\sin$ by geometrical means. |

Why is it impossible to define multiplication in Presburger arithmetic? @MJD Presburger arithmetic is an axiomatic system. People claim that it is impossible to define multiplication within this system. Why? |

How to prove that $\lim\limits_{x\to0}\frac{\sin x}x=1$? How do we know that sin x is equal to x for small values? |

The inverse of the inscribed angle theorem I am sorry. I usually don't ignore the orientation of angles. I should've made that clear beforehand. |

The inverse of the inscribed angle theorem In the second case, the sign of the angle $\angle ACB$ is negative. The equation $2\angle ACB=\angle AMB$ does not holds if the signs do not match. |
