I'm having difficulties in using the Heaviside function in Maple. My heaviside function is (t-tau), and I'm having trouble integrating tau from zero to t. After integration, the expression still shows an integral. Is it because when tau = t, the heaviside becomes zero? Any and all help is appreciated. Attached is the actual sheet. The 2nd to last and last steps are the steps or concern.... **** This problem has been overcome *****

How do use an equation to create a list/array?

e.g y=x*5+1

for x from 0 to 1 in increments of 0.1

answer should look similar to:
[0,1]
[0.1,1.5]
[0.2,2]
[0.3,2.5]
