question: consider the function $y = 2sin(x)$ for $0^{circ}leq xleq360^{circ}$. 1. graph the function: plot the function $y = 2sin(x)$ on a coordinate plane. label the x - axis as \angle (degrees)\ and the y - axis as \y - value\. mark the coordinates of all key points where the graph intersects the x - axis, reaches its maximum, or minimum within the given interval.
Answer
Explanation:
Step1: 确定关键点
当(y = 0)时,(2\sin(x)=0),(x = 0^{\circ},180^{\circ},360^{\circ});当(\sin(x)=1)时,(y)取最大值(2),此时(x = 90^{\circ});当(\sin(x)= - 1)时,(y)取最小值(-2),此时(x = 270^{\circ})。
Step2: 绘制图像
在坐标平面上,以“角度(度)”为(x)轴,“(y)值”为(y)轴,标出上述关键点并绘制(y = 2\sin(x))图像。
Answer:
按步骤绘制出(y = 2\sin(x))在(0^{\circ}\leq x\leq360^{\circ})的图像,关键点坐标为((0,0)),((90,2)),((180,0)),((270, - 2)),((360,0)) 。
