1) Create a function called step_fn(t).
This is also common to call this function u(t) or u_fn(t)
Input: time vector
Output: a vector of the same length with values of 0 if t<0, and 1 otherwise
2) Create a function called ramp_fn(t)
This is also common to call this function r(t), r_fn(t) or tu(t)
Input: time vector
Output: a vector of the same length with values of 0 if t<0, and t otherwise
3) Create a function called g1_fn(t)
This function should be equal to step_fn(t) + ramp_fn(t) – ramp_fn(t-3) -3*step_fn(t-5)
4) Plot the following functions (can put on one plot or use subplots — decide how to best present the functions).
u(t)
u(t-2)
2u(t)
-3u(t+2)
5) Plot the following functions (can put on one plot or use subplots — decide how to best present the functions).
r(t)
r(t-2)
2r(t)
-3r(t+2)
6) Plot the following functions (can put on one plot or use subplots — decide how to best present the functions).
sin(t)u(t)
sin(t)u(t-π)
sin(t-π)u(t-π)
7) Plot the following functions (can put on one plot or use subplots — decide how to best present the functions).
g(t)
g(t-2)
g(2t)
g(t/2)
8) Write a script to determine the balance in a saving account at the end of every year for n = years. The account has an initial investment of A$ and the interest rate is r, and compounds annually. Show the script should request
Initial investment amount
Interest rate
years
if should create a vector for number of year [1:n], and the balance after each year
Balance = A(1 + r/100)n
