The covid -19 is the one diseces for which the world even don’t know . In these days of pandemic that cause to the lockdown, Rahul’s bussiness is in Loss. On 0th day of Lockdown the loss was Rs P, then Rs Q on the 1st day. Rahul observed loss as a function and wanted to calculate the loss on nth day of the Lockdowni.e. F(n)=F(n−1)+F(n−2)+F(n−1)∗F(n−2)F(n)=F(n−1)+F(n−2)+F(n−1)∗F(n−2) You have the loss on 0th day and the 1st day of pandemic time. You have to find the loss on nth day.

Write a function in MATLAB that has two inputs: - A shear load (as the first input) - A tensile load (as the second input)   Have your function return one output, a string with the name of the lowest grade material from Table 1 that can handle those loads.

Write a MATLAB function that calculates the approximate value of six(x) using the Maclaurin series approximation from x-0 to xi+1 six(x) = x -+-+. 3 5 The function should accept 3 parameters: value of x, number of significant figures accuracy i.e. n, and the maximum number of iterations. In the function, use ɛ = (0.5 × 10²-" )% in order to continue until the ɛa falls below this criteria. The function should return 3 values: the approximate value of arctan(x) at the end of the program, final ɛg and the number of iterations it took. Submit short snapshots showing the program running.

Write a MatLab user-defined function that determines the coefficients of a cubic polynomial, f(x)=a₂x³ + a₂x² + a₁x + a that best fits a given set of data points. The function should also calculate the overall error E. Name the function [a,Er] = CubPolFit(x,y), where the input arguments x and y are vectors with the coordinates of the data points, and the output argument a is a four-element vector with the values of the coefficients a3, a₂, a₁, a. The output argument Er is the value of the overall error. " (a) Use CubPolFit to find the cubic polynomial that best fits the data in the rubber tension tests (see lecture slides): Curve fitting - polynomial regression - Example A tension test is conducted for determining the stress-strain be- havior of rubber. The data points from the test are shown in the figure, and their values are given below. Determine the fourth order polynomial that best fits the data points. Make a plot of the data points and the curve that corresponds to the…
