为了在计算器上计算cos（x）： 输入输入角度。 在组合框中选择度数（°）或弧度（rad）的角度类型。 按 = 按钮计算结果。

line\:(1,\:2),\:(3,\:1) f(x)=x^3 ; prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) \frac{d}{dx}(\frac{3x+9}{2-x}) (\sin^2(\theta))' \sin(120) \lim _{x\to 0}(x\ln (x)) \int e^x\cos (x)dx

Trigonometry mainly provides six functions for sine (sin), cosine (cos), and tangent (tan), also its reciprocal functions cosecant (csc), secant (sec), and cotangent (cot). These processes help in solving angle and distance related problems in both 2D and 3D surroundings.

The value of cos^2 (32) is 0.71918…

2 天之前 · 余弦(cos)函数是三角函数的一种。在直角三角形中，余弦函数定义为邻边与斜边的比值。具体来说，在Rt ABC中，∠C = 90°，∠A的余弦是它的邻边比三角形的斜边，即cosA = b/c，也可以写为cosa = AC/AB。

2024年10月3日 · 计算角度 x x 余弦的公式为： \cos (x) = \frac {\text {邻边长度}} {\text {斜边长度}} cos(x) = 斜边长度邻边长度. 在半径（斜边）为 1 的单位圆中，余弦函数给出圆上某一点的横坐标。 计算 30 度（即 \frac {\pi} {6} 6π 弧度）的余弦： \cos (30^\circ) = \cos\left (\frac {\pi} {6}\right) = \frac {\sqrt {3}} {2} \approx 0.866025 cos(30∘) = cos(6π) = 23 ≈ 0.866025. 余弦函数在解决直角三角形相关问题、物理学中模拟波形以及计算机图形学算法中渲染场景时至关重要。 余弦函数 …
