The (i) in this context represents the imaginary unit, which is the square root of -1. It is commonly used in complex numbers to distinguish the imaginary part from the real part.
In this scenario, (i) is used to represent the vertical component of the force, which is imaginary. This is necessary because the force is acting at a 90-degree angle from the horizontal axis.
The value of (i) is calculated by taking the square root of -1. In this case, the force is given as 3.86 N, and the vertical component is represented by (i). This means that the force acting in the upward direction is 3.86 N(i).
The use of (i) in complex numbers allows for the representation of both real and imaginary numbers, which are essential in many scientific and mathematical calculations. In this particular case, it helps to accurately describe the force acting on an object at a 90-degree angle.
Yes, (i) has many other uses in science, such as in electrical engineering, quantum mechanics, and signal processing. It is a fundamental concept in complex analysis and has numerous applications in various fields of science and engineering.
