Below is the code for matlab for calculating the first and second-order derivatives using analytic expressions.
#code begins
h = 0.1; f = [800 732 592 290 5]; t = [0 3.9 7.5 13.9 20];
for i = 1:length(f) - 1
first_derivative(i) = (f(i+1) - f(i))/h; end;
for i = 2:length(f) - 1
second_derivative(i) = ( f(i+1) - (2*f(i)) + f(i) )/(h*h);
end;
#code ends
Both the expressions for the derivatives are second-order accurate as the higher-order terms are neglected.

My code for calculating the first derivative is the second image Compute second derivative O solutions submitted (max: 10) You are provided with a set of data for the position of an object over time. The data is sampled at evenly spaced time intervals. Your task is to find a second order accurate approximation for the acceleration at each point in time. Write a Matlab function that takes in a vector of positions x, the time interval between each sampled...

i need the answer to be on a MatLab window 1. Consider the following equation, which represents the concentration (c, in mg/ml) of a drug in the bloodstream over time (t, in seconds). Assume we are interested in a concentration of c2 mg/ml C3te-0.4t A. Estimate the times at which the concentration is 2 mg/ml using a graphical method Be sure to show your plot(s). Hint: There are 2 real solutions B. Use MATLAB to apply the secant method (e.g....

For this exercise we will run a regression using Swiss demographic data from around 1888. The sample is a cross-section of French speaking counties in Switzerland This data come with the R package datasets. The first step is to load the package into your current environment by typing the command libraryldatasets) in to the R console. This loads a number of datasets including one called swiss. Type help/swiss) in the console for additional details. The basic variable definitions are as...

I only need help with part B. I need help with the sketch and all of B, not just the first part (like others have answered previously.) THIS IS THE PART I REALLY NEED HELP WITH 1.

The referee has two envelopes (numbered 1 and 2 for the sake of this problem, but when the game is played the envelopes...
Could you please help me with questions 1a-1b please? ( since i could only find the formula needed for 1a, if u aren't sure with 1b u can just do 1a but please dont reply "no enough data given " because i have a lil systemical problem with replying the comments) * the first question was asked to complete the anova table ( table 9.1 in the picture ) by using the formulas ( in the pictures) * I have...
