百度试题 结果1 题目证明\( \sin^2 \theta + \cos^2 \theta = 1 \)。相关知识点: 试题来源: 解析 证明:根据三角恒等式,我们知道 \( \sin^2 \theta + \cos^2 \theta \) 是三角函数的基本恒等式,它恒等于1。反馈 收藏
接下来，我们可以利用三角恒等式(\sin^2\theta + \cos^2\theta = 1) 来证明：考虑一个直角三角形...
化简sin(theta)^2+cos(theta)^2+tan(theta)^2-1 sin2(θ)+cos2(θ)+tan2(θ)−1sin2(θ)+cos2(θ)+tan2(θ)-1 使用勾股恒等式。 1+tan2(θ)−11+tan2(θ)-1 合并1+tan2(θ)−1tan2(θ)-中相反的项。 点击获取更多步骤......
我们可以过终边与单位圆的交点作垂线,求对应的三角函数值。因为圆周上的点到圆心的距离为1,于是\sqrt{x^2+y^2}=1,因此我们可以发现交点的坐标x和y的值就对应了\cos\theta和\sin \theta。 无论\theta是多少,\sin \theta与\cos \theta我们只需要去找终边与单位圆的交点坐标x,y就可以了。
将(sin(θ)+cos(θ))2(sin(θ)+cos(θ))2重写为(sin(θ)+cos(θ))(sin(θ)+cos(θ))(sin(θ)+cos(θ))(sin(θ)+cos(θ))。 (sin(θ)+cos(θ))(sin(θ)+cos(θ))(sin(θ)+cos(θ))(sin(θ)+cos(θ)) 使用FOIL 方法展开(sin(θ)+cos(θ))(sin(θ)+cos(θ))(sin(θ)+...
