|dw:1444276721997:dw|Mmm k we've got some kind of function

2. zepdrix

The length of the interval is 2, ya? And we want to split that length of 2 into 4 equal parts. So what will be the width of each rectangle? :)

3. anonymous

yes and they want to know midpoint

4. anonymous

each width should be 1/2
