Probability Density Function for a Pendulum?

Click For Summary
SUMMARY

The probability density function for a simple pendulum, using the small angle approximation, is defined as 1/(2πθmax) sec(√(g/L)t). This equation represents the probability density as a function of the angle of displacement from the vertical position. The discussion emphasizes the need to clarify the random variable in question, which is crucial for accurately interpreting the probability density in the context of pendulum motion.

What is the probability density equation as a function of angle for a simple pendulum using the small angle approximation?

I got 1/(2 pi θmax) sec(sqrt(g/L)t) but it doesn't seem right.
