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...
In standard condition, the period(difference between two successive crests or troughs) of the sine and cosine functions is2π. In other conditions, the period of the function can be calculated as- T=2πω Answer and Explanation:1 The given graph has the symmetry a...
The graph of y=−cosx is a reflection of the graph of y=sin(x+π2) in the x-axis. Graph of Trigonometric Functions: We know that all trigonometric functions are periodic in nature and graphs are repeating after a c...
The circles have markings whose intersections with orthogonal radii on the first disc give the sine and cosine of the wind angle. The second face shows useful formulae and tables.
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 Sine Function produces a very beautiful curve, but don't take our word for it, make your own!Sine FunctionFirst, read the page on Sine, Cosine and Tangent.Now you will know that the sine of any angle is the length of the far side of the triangle (the "opposite") divided by ...
These graphs each start at x = 0 and repeat every 2π units (for sine, cosine, secant, and cosecant) or every π units (for tangent and cotangent). Shifting these graphs up or down is easy; shifting them sideways can seem... less easy. MathHelp.com...
