When I'm using formulas such as T = 2(pi) / w I thought Pi should be in Radians as w is in rad/sec yet when I look at an example it uses 3.14. Why is it 3.14 instead of 180?

The number 3.14 is used as an approximation for the mathematical constant Pi (π). This is because Pi is an irrational number with an infinite number of decimal places, making it impossible to use the exact value in equations. 3.14 is a commonly used approximation that is accurate enough for most scientific calculations.
Yes, a more accurate value of Pi can be used in the equation. However, for most scientific calculations, the approximated value of 3.14 is precise enough and using a more accurate value would not significantly impact the results.
The value of 3.14 for Pi was determined through various mathematical methods such as approximations, geometric constructions, and numerical methods. The most accurate value of Pi to date has been calculated to over 31 trillion decimal places.
Pi is important in scientific equations because it is a fundamental mathematical constant that is used in many calculations involving circles, spheres, and other curved objects. It is also a key factor in trigonometric functions and many physical laws and principles.
No, Pi cannot be replaced with a different constant in the equation T = 2(pi) / w. Pi is unique and is the only constant that can be used in this equation to accurately represent the relationship between the period (T) and angular frequency (w) of a oscillating system.
