x -4 -2 0 1 2 3 y -10 3 8 25 52 36 For the same data given for 7_1, a) Plot the data points with a circle marker (MATLAB). b) Plot the unique interpolating polynomial (passes exactly through each point) and print the equation of the polynomial (in the form y = a, x"+ am1x^-1+ .. + a;x + ao) to the screen using fprintf. Don't use polyfit & polyval for this problem; use the backslash on the Van der Monde matrix & construct the function handle and use fplot. c) Plot the linear splines between each pair of points using interpl. d) Plot the "not-a-knot" cubic spline using interpl

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.

Please use python and show codes

Write in C Asks the user for the magnitude (distance), in meters, and the heading, in degrees of the navigation to way-point Alpha. - Decompose the vector into x and y components and output the magnitude and direction (North, West, South, or East are the only reliable headings on the sub's compass) of the x component and then they component. The x component is the magnitude multiplied by the cosine of the angle. They component is the magnitude multiplied by the sine of the angle. Determine compass direction depending on weather the vector component is positive or negative. This step has to be repeated for waypoint bravo. Output the total distance traveled by the submarine from the starting point till it reaches point bravo. Output the distance from the starting point till point bravo (the true distance, not the distance traveled). Ask the user for the target bearing (0 to 25 degrees, float) and range (range in meters, integer). Output a firing solution as follows Range 100 to 300 301…
