[Wolfram Alpha 應用示例]
.B3.1-5 三角函數的圖形
.指令: Plot[{sin(x),cos(x),tan(x)},{x,0,2*Pi}]
.請留意0到90度之間的函數值變化: sin(x),tan(x)遞增,cos(x)遞減

.
[Wolfram Alpha Application]
.A web-based way to plot the graph of any function(trigonometry here).
.Just input the function name and the range of angle in radian you want,and you will get the graph in return.
