As an EE, I spent my whole career using complex numbers. As an example, in circuit math, inductors and capacitors are represented using complex numbers. Hardware is often designed in the 4th dimension using Laplace and Fourier transforms, which require the use of complex numbers. I have watched a few of this guy's videos, and he is pretty good.

[@sleeplessdistrict3897]

A someone interested in majoring electrical engineering, I didn’t realize the concept could even be applied. That’s really interesting

[@carultch]

@@sleeplessdistrict3897In Electrical Engineering, these numbers are called j instead of i, because i already has a full time job in EE to stand for current. These numbers enable you to keep track of components such as capacitors and inductors, in the same way you keep track of resistors, except with an equivalent concept of impedance that uses imaginary numbers. This allows you to combine such components in series and parallel, the same way you combine resistors in series and parallel, in order to predict the behavior of a circuit with all three kinds of passive components. An example problem you might solve in EE with these numbers is as follows: A resistor (R = 100 ohms) and an inductor (L = 100 millihenry) are in series, supplied by an AC voltage source defined by V=A*sin(w*t), with A=170V and w = 377 rad/s. What is the amplitude of the current through the circuit, and the phase shift from the original voltage waveform? Solution: Impedance of the resistor, Zr = R Impedance of the inductor, ZL = j*w*L Voltage waveform expressed as a phasor: V = A + 0*j Current waveform expressed as a phasor: I = ir + ij*j We are interested in determining values of ir and ij, the real and imaginary components of I. Once we have those, we combine them in Pythagorean theorem to get magnitude, and use arctangent to get the phase angle. Add up the impedances in series: Znet = Zr + ZL Znet = R + j*w*L Apply the impedance extension of Ohm's law to relate voltage to current: V = I*Znet Solve for I: I = V/Znet Substitute Znet, and V = A + 0*j: I = A/(R + j*w*L) Use complex conjugates to clear the j out of the denominator, by multiplying by 1 in a fancy way: 1 = (R - j*w*L)/(R - j*w*L) I = A/(R + j*w*L) * (R - j*w*L)/(R - j*w*L) (R + j*w*L) * (R - j*w*L) = R^2 + w^2*L^2 I = A*(R - j*w*L)/ (R^2 + w^2*L^2) Therefore: ir = A*R/(R^2 + w^2*L^2) ij = -A*w*L/(R^2 + w^2*L^2) Magnitude of I = sqrt(ir^2 + ij^2) Magnitude of I = A/sqrt(R^2 + w^2*L^2) = 1.6 Amps Phase angle of I = arctan(ij/ir) = arctan(-w*L/R) = -0.36 rad or -20.7 degrees Equation for I(t) = 1.6 Amps * sin(377 rad/s *t - 0.36 rad)

He is right sqrt(25-24) you find it by looking into it. He is not exactly saying about converting from irrational to rational. The calculation does it in that way. If it is sqrt(a-b) it can produce rational, irrational or complex number. It is the power of mathematical abstraction.

When I was younger in grade school it was my absolute favourite subject, but around middle and high school where more advanced and seemingly obscure concepts were introduced and curious that I am ever questioned their validity I was always struck down, always told that thats just the way it is. I absolutely lost it, I hated it. Mathematics became something that made me disgusted with school. How can they be teaching us stuff that they themselves absolutely do not understand. The hypocrisy was unbelievable. I switched my whole academic career in favour of english and social sciences as in those subjects questioning things and gaining intuition is validated, its expected and important. We need to rethink our education model. No more pushing people along without mastery, you're just dooming kids to a life of obeying orders without needing understanding.

The term "surd" refers to the expression, not the result. That is, a surd is "the nth root of p". In this case the expression "the 2nd (square) root of 1", which resolves to the integers 1 and -1. Other surds, such as the square root of 2, don't resolve to integers, they are irrational and usually remain expressed in their surd form to avoid approximation.

How is the square root of one a "surd"?

[@akshat8429]

A surd is just the root of a number. And 1 is a number

[@armpitpuncher]

@@akshat8429 No, a surd is a root that can not be simplified to a rational number. The square root of 1 can be simplified. This teacher is using either wrong, or using some unconventional terminology.
