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/...
Look at the graph of thesine functionandcosine function. Notice that the value of the functions oscillates between -1 and 1 and it is defined for all real numbers. Thus, for each of the sine and cosine functions: Domain:The domain of the functions is the set ℝ (or) (-∞, + ∞)...
The graph of the sine function begins at the origin, has a period (length of a cycle) of 2π, and an amplitude (distance from the center) of 1. We can adjust these values in order to transform the graph of this function. f(x)=Asin(Bx)+CAnswer and Explanation: Become a Study...
Graph the Sine and Cosine functions on the coordinate plane using the unit circle. Determine the domain and range of the Sine and Cosine function. Determine the period of the Sine and Cosine Function. Determine the period of the Sine and Cosine functions. ...
We can label the values where the circle intersects the axes because we know that the radius of the unit circle is 11 unit. We can still construct a triangle within the unit circle with the angle starting from the positive xx axis. Looking at the trigonometric ratios of sine and cosine, ...
那cosine函数图像呢? 答案 正弦函数图像的斜率是连续变化的,不同的t值其斜率也不同相关推荐 1对正弦函数图像的斜率不断变化,并不会产生在不同的t值相同的值the graph of the sine function change its slope continually and would not likely yield the same value at a different value of t正弦函数图像的...
Cosine or cos x is a periodic function in trigonometry. Consider a unit circle centered at the origin of the coordinate plane. A variable point P moves on the circumference of this circle. From the figure, we observe that P is in the first quadrant, and OP makes an acute angle of x ...
