怎样用maple求解隐函数方程和含参的积分。 请问用Maple(或者别的数学软件也可以)怎么绘制隐函数方程...

因为不知道你的J(x)具体表达式是什么,只能举例说明了
积分函数int,比如要求sin(x)的积分,则int(sin(x),x)即可
若要求sin(x)在区间(-1,1)上的定积分则写作int(sin(x),x=-1..1)
solve函数的语法就是solve(方程,未知数),比如求方程x^2-x-1=0的解,写作solve(x^2-x-1=0,x)
假设你的J(x)是a*sin(x)/x在区间(0,正无穷)上的积分,那么你的问题可写作
solve(x^2=3-2*int(a*sin(x)/x,x=0..infinity),x)
