当我们更新了三角函数的定义方式后,自然就会遇到三种函数的值的相互关系,比如已知$\sin\theta+\cos\theta$[四则运算之一,加法]的值,如何求解关于$\sin\theta$和$\cos\theta$之间的四则运算的剩余运算[减法、乘法、除法],是本博文探讨的重点。

Find all θθ such that sinθθ and cosθθ are both rational number. I thought this question might have been asked by someone else, but I couldn't find any. Currently I'm studying Pythagorean triple, so naturally I put XX=cosθθ and YY=sinθθ, then X2+Y2=...
