i(t)=(V/R) * (1-e^-(R/L)(t))
(a) Define an anonymous function answerE that returns i(t) given input t.
(b) The final value for the current is 2 amps. Find a time tm when the
current is at least 99% of the nal value but strictly less than 2. Store
this value in the variable answerF.
(c) Create a vector in answerG using linspace with ten evenly spaced
elements where 0 as the first element and tm as the last element.
(d) Create a vector in answerH which contains the current at each time in
vector answerG.
