[sage-support] Integration

2013-12-09 Thread Santanu Sarkar
I want to find the following integration. I=integral_{t=x}^y I_{x<=y}t, where I_{x<=y} is the indicator function whose value is 1 when x<=y, else 0. So, value of I=(y^2-x^2)/2 if x<=y =0 if x>y Does Sage provide this kind of symbolic integration? -- You receiv
