[图形计算器]Desmos

一、图形计算器

var elt = document.getElementById('calculator');
var calculator = Desmos.GraphingCalculator(elt);
calculator.updateSettings({xAxisArrowMode: Desmos.AxisArrowModes.POSITIVE,yAxisArrowMode: Desmos.AxisArrowModes.POSITIVE});
calculator.setExpression({id:'graph1', latex:'y=mx^2'});
calculator.setExpression({id:'slider1', latex:'m=2', sliderBounds: {min: -3, max: 3, step: 0.5}});
calculator.setExpression({id:'graph2', latex:'x^2+y^2=4'});
calculator.setExpression({id:'graph3', latex:'y^2>4x'});
calculator.setExpression({id:'graph4', latex:'y=x-2'});

提示：你可以在上述的图形计算器中的左侧输入函数，方程，不等式等等。

二、四则运算计算器
