lf u = (l,0) and v = (1, 1) what is the angle in degrees between u and v? in matlab

The angle between two vectors u and v can be calculated using the dot product formula as cos(theta) = (u . v) / (|u| |v|), where |u| and |v| are the magnitudes of vectors u and v.

In Matlab, we can write the code as follows:

main.m
u = [1, 0]; % (l,0)
v = [1, 1]; % (1, 1)
cos_theta = dot(u, v) / (norm(u) * norm(v));
theta = acosd(cos_theta); % theta in degrees

Here, u is the vector (l, 0) and v is the vector (1, 1). We first calculate the dot product of u and v, and then divide it by the product of their magnitudes to get cos(theta). Finally, we calculate theta in degrees using the acosd function.

So, the angle in degrees between u and v is 45 degrees.
