Question

What will be the command to find the current through a 1H inductor (no initial current) whose voltage changes by v=t^2?

(a) int(‘t^2’)

(b) intg(‘t^2’)

(c) int(t^2)

(d) Cannot be determined

This question was addressed to me in exam.

My doubt is from Integration topic in portion Beyond the Basics of MATLAB

Answer 1

Right choice is (c) int(t^2)

To explain I would say: We can only integrate our voltage equation to get the current as a function of time. The syntax for int(t^2) is the correct syntax for the int() command. The rest is wrong since the int() command does not take string arguments.
