Can the phase angle not be obtained by noting that at t = 0 the sinusoidal is at a minimum?haruspex said:

Rearranging a formula involves isolating a specific variable on one side of the equation. This can be done by using algebraic operations such as addition, subtraction, multiplication, and division. The goal is to get the variable you want to solve for on one side of the equation and all other variables and constants on the other side.
The phase angle in a formula represents the angular difference between two waves or signals. It is typically measured in degrees or radians and can be positive or negative depending on the direction of the wave or signal.
To calculate the phase angle, you need to know the frequency and time period of the wave or signal. The formula for calculating phase angle is phase angle = (360 * time period * frequency) / 360. This will give you the phase angle in degrees. If you want the phase angle in radians, you can use the formula phase angle = (2 * pi * time period * frequency) / (2 * pi).
Yes, most scientific calculators have a function for calculating the phase angle. Look for a button labeled "phase" or "angle" on your calculator. If you are using a graphing calculator, you can also use the "phase" function in the "math" menu.
Rearranging formulas allows us to solve for a specific variable and manipulate equations to better understand the relationship between different variables. Working out the phase angle is important in fields such as physics and engineering, where understanding the phase difference between waves or signals is crucial in designing and analyzing systems and circuits.
