for some reason i keep getting the math domian error for acos. can someone tell me how to fix my code please? also im a begginer so thats why the code isn't complex nor as efficient as it could be

Program 2: This program is meant to help you get practice with writing programs to perform mc numerical calculations, and specifically to give you practice with vector calculations. Dot product of two vectors 4 is given by: V1V2=V1xV2x+V1yV2y+V1zV2z=V1V2cos() Write a program that calculates the angle between two points, as seen by an observen. Your program should read in: - The 3D position of an observer - The 3D position of the first observed point - The 30 position of the second observed point Then, it should calculate and output, in degrees, the angle between the points from the viewer's perspective. The steps for doing this are: - Read in the points from the user. Assume the points will be some (x,y,z) coordinates. - Calculate components of the two displacement vectors from the observer to each of the observed points - Calculate magnitudes of the two displacement vectors - Calculate the dot product between the vectors - Use the dot product to calculate the angle between the two observed points. Note that the dot product of two normalized vectors gives the cosine of the angle between those vectors. - Output the answer in degrees Before beginning coding you should stop and think briefly about the variables you will need for your program. Enter the coordinate of the observer separated by conas: 1,1,1 Enter the coordinate of the first observed point separated by comes: 2,2,2 Enter coordinate of the second observed point separated by comas: 5,3,3.
