Answer 2

It looks like you're trying to describe a harmonic motion using trigonometric functions. In your expression, it seems you want to represent the displacement (X) of an object over time (t) with a cosine function. Here's how you can break down the given expression:

1. X = 7cos(8πt)

   • This equation represents the displacement (X) of an object at time (t) using a cosine function.
   • The amplitude (A) is 7, which means the maximum displacement of the object is 7 units.
   • The angular frequency (ω) is 8π, which determines how fast the object oscillates.
   • The cosine function is used because it's a common way to describe simple harmonic motion.

2. t = 10sXm

   • It appears you're trying to relate time (t) and displacement (X) using this equation.
   • 10sXm is not a standard notation, so it's not clear what it represents without additional context. It could be a scaling factor or some specific quantity related to the problem you're working on.

Without more information or context, it's challenging to provide specific values or interpretations for "sXm" and "w." If you can provide more details or clarify what those terms represent, I'd be happy to help further.
