This subject covers the foundational concepts of number and quantity, focusing on real numbers, complex numbers, and their applications in various mathematical contexts.
Complex numbers are used in engineering, physics, and technology to solve real-world problems.
They let engineers and scientists represent signals that change over time, model waves, and solve equations that real numbers can't handle.
Even though they’re called "imaginary," complex numbers have very real uses!
Using complex numbers to describe the voltage in an AC circuit.
Modeling the movement of sound or light waves.
