I need help with coding this for matlab please.  Plotting Discrete-TimeSignals  Use stem to plot the discrete-time step-function:  n = -10:10;   f = n >= 0;  stem(n,f)  Make stem plots of the following signals. Decide for yourself what the range of n should be. f(n) = u(n) − u(n − 4)  g(n) = n · u(n) − 2 (n − 4) · u(n − 4) + (n − 8) · u(n − 8)  x(n) = δ(n) − 2 δ(n − 4)  y(n) = (0.9)n (u(n) − u(n − 20))  v(n) = cos(0.12 πn) u(n)

USING PYTHON NOT MATLAB We can use the sum of the first n terms of the Taylor series of e x with a = 0 to estimate the value of the exponential function. Using a logarithmic y axis, plot the fractional error in the estimated e x (compared to numpy.exp(x)) as a function of n (n ranging between 1 and 80) for (a) x = 15 and (b) x = −15. [You can plot the two cases either as different curves on the same plot or in different plots, whichever is clearer.] Discuss the contributions of truncation and roundoff to the fractional error for the different values of x and n. Also discuss how you could reduce truncation and roundoff errors in order to estimate e x more accurately using the Taylor series.

I need help with this problem involving Boolean variables and I am absolutely lost on this problem since I never seen anything like it.   If (f(w,x,y,z) = (x+yz) + (wx). What is f(1,0,0,0) There is a line over (x+yz), there is a line over letter z, and there is a line over letter w.

Using Matlab, code the following:The paper cup has Radius R2 = l.5(R1), height (h), volume V = 716 cm3 ,and surface area (S). The height, volume, and surface area of the cup are given by: V =πh(R1^2+R2^2+R1R2)/3 S = π R1^2+ π (R1+R2)√(R2 − R1)^2 + h^2 Determine R1, R2, and S of the paper cups with heights h = 8, 10, 12, 14, and 16 cm. • Method 1: Simulate Equations without using a for loop. • Method 2: Simulate Equations using a for loop. Display results to the screen tabulated Hint: You may need to transpose the vectors before printing to the screen.
