In problem 1, that is the question number 1, our given function f of t, it gives 1 if t lies between 0 to 1, it gives 0 if t lies between 1 to 2, it gives 1 if t lies between 2 to 3, it gives 0 if t greater than equal to 3.

So, to find the laplace of the given function f of t, first of all we can write the given function f of t by using the unit function, we can express this function like as 1 multiply 2, that is u naught negative u1 of t plus 0 times of u1 of t negative u2 of t plus 1 times of u2 of t negative u3 of t plus 0 times of u3 of t.

So, this will is equal to the 1 times of u naught negative u1 of t plus 1 times of u2 of t negative 1 times of u3 of t.

So, now further again plus 0, further apply the laplace transform on both side, the laplace of u naught of t negative laplace of u1 of t positive the laplace of u2 of t negative laplace of u3 of t, so that is 1 over s negative e to the power of negative s over s plus e to the power of negative s twice of s over s negative e to the power of negative 3s over s...
