sin squared plus cosine squared equals to a constant. 因此,证明了sin方+cos方始终为常数。 经过这些解释和推理,我们已经更好地理解了sin方+cos方的几何意义以及它为常数的证明。接下来,我们将进一步分析和讨论sin方+cos方在不同角度取值变化特点,以及它与其他函数的关系以及在实际应用中的作用和意义。 3. 分...
sin(x) = √(1 - cos²(x)) It's important to note that the square root here represents taking the non-negative value. This is because in trigonometric functions, the range of sin and cos is [-1,1], so their squared values are all within [0,1]. After taking the square root, ...
