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/...

whether its sine or cosine or anything, can be thought of a 'slide'. Totranslatea graph, all that you have to do is shift or slide the entire graph to a different place.
Know what sine and cosine waves are and how to graph their respective waves. Read more about the calculation of its period and amplitude through...
Trigonometry graphs of sin, cos and tan functions are explained here with the help of figures. Learn how to plot the graph for trig functions with an example here at BYJU'S.
Cosine Function Inverse Trigonometric Ratios Trigonometric Ratios Important Notes on Sine Function: Sine can be mathematically written as: sin x = Opposite Side/Hypotenuse = Perpendicular/Hypotenuse f(x) = sin x is a periodic function and sine function period is 2π. The domain and range of the...
The sine function is expressed by the equation f(x)=sin(x), and its graph looks like this: The sine function f(x) = sin(x) Highlighted here is the sine graph period. As we can see, the sine wave "begins" at the origin, climbs to a maximum value of y=1, passes through y=0...
Sine is one of the three most common (others are cosine and tangent, as well as secant, cosecant, and cotangent). The abbreviation of sine is sin e.g. sin(30°)sin(30°). The most common and well-known sine definition is based on the right-angled triangle. Let's start with ...
Now, to check whether the value is $+\infty \text{ or }-\infty $ , we should use the graph of $y=\tan \left( x \right)\text{ at }x={{270}^{\circ }}$ From this graph, we can clearly see that $y=\tan \left( x \right)\text{ approaches }+\infty \text{ a...
Cosine: Start at 1, no initial impulse So cosine just starts off... sitting there at 1. We let the restoring force do the work: Again, we integrate -1 twice to get $\frac{-x^2}{2!}$. But this kicks off another restoring force, which kicks off another, and before you know it...
