Matlab code plot the sin(x) function and 10 evenly spaced error bars, representing the error in approximation of x-x^3/6. Label the axes and add a grid and legend. Use red with a dashed line for sin(x). Attach here the file with code and graph

PYTHON JUPYTER NOTEBOOKS please show code clearly.  create a program for lower triangular system L x = b. The algorithm is described in the image for i and j with offset 1. Recall that NumPy and Python have offset 0 for their sequence data types.

You have been provided with the data for the last day of the previous month so you can start by calculating the daily data for the first of the month For the first state for the first day of the month (not the last day of the previous month) enter the following formula into the upper cell for the column for “Daily Confirmed cases” = Current day’s cumulative Confirmed cases – the Confirmed cases for the day before (i.e. the last day of the month). This will yield the number of daily confirmed cases for the first of the month. (Use Excel cell referencing in the formulas)

Give a quick explanation of the character set.
