回答：1) 方法一: 1.先画 sin( x) 2.将每一个周期[0:2pi] 缩小到 [0:pi/2]. 现在[0:2pi]区域内包括4个周期. 3.将函数图像整体左移pi. 4.将函数幅度增加为原来的2倍 5.将函数图像关于x轴对称. 方法二: 选取几个特殊点 x=-pi/2, -3pi/8, -pi/4, -pi/8, 0, pi/...
Looking at the trigonometric ratios of sine and cosine, we can say that: \sin(\theta)=\frac{a}{1} \; \text{so} \; a=\sin(\theta) \cos(\theta)=\frac{b}{1} \; \text{so} \; b=\cos(\theta) \tan(\theta)=\frac{a}{b} \; \text{so} \; \tan(\theta)=\frac{\sin...
sin-1x + cos-1x = π/2, when x ∈ [-1, 1]Derivative of Arccos x Let us find the derivative of y = cos-1x. By the definition of arccosine, y = cos-1x can be written as cos y = x. Differentiating this on both sides with respect to x using the chain rule,-...
In other conditions, the period of the function can be calculated as- T=2πω Answer and Explanation:1 The given graph has the symmetry about they-axis. So, it is the graph of the cosine function. Here the maximum displacement from the... ...
The graph of a standard sine or cosine function will repeat once every 2\pi radians, and will vary between \pm 1. The amplitude may be changed by a multiplicative coefficient, the frequency may be changed by multiplication of the argument, and the vertical level may be changed by an ...
The cos graph - or cosine graph - is the representation of the cosine function in the Cartesian plane. Like the sine graph, it is a wave.
The tangent function can also be expressed as the ratio of the sine function and cosine function which can be derived using a unit circle. Hence, the formulas for tan x are:tan x = sin x/cos x tan x = Opposite Side/Adjacent Side = Perpendicular/Base...
