Calculate the angle between two points over a period of time

Question

I would like to calculate the angle between two points in a coordinate system over a period of time.

X: Time Y: Values of a currency Pair.

For example:

At 10AM(X1) the pair was at 1.1110(Y1) Euros. At 11AM(X2) the pair was at 1.1190(Y2) Euros.

Now I would like to calculate the angle. Do I need to calculate the DeltaX like: Delta 1 hour = 60 min = DeltaX = 60?

Or do I need to convert the time to something else?

I tried it like this already but the outcome seems to be not right.

x1 = 0
x2 = 60
y1 = 1.1110
y2 = 1.1190

delta_y = ((y2)-(y1))**2
delta_x = ((x2)-(x1))**2
radian = math.atan2(delta_y, delta_x)
degree = radian*(180/math.pi)
print(degree)

Outcome: 0.0002291831180511074

Answer 1

I think the following should work and convert your values into the right angle in degree:

import math

x1 = 0
x2 = 60
y1 = 1.1110
y2 = 1.1190

#Calculate the length of the opposite and adjacent sides
delta_y = y2 - y1
delta_x = x2 - x1

# Calculate tangens
tan = delta_y / delta_x

# Calculate inverse function of tangens (arctan)
alpha_rad = math.atan(tan)

#Calculate alpha from rad to degree
alpha_degree = alpha_rad * (180/math.pi)

print(alpha_degree)
