In this video, we're going to talk about certain Greek alphabet symbols that you might see in a typical math course or in chemistry or physics. So the first one is the symbol alpha. In physics, this symbol typically represents angular acceleration. Sometimes you'll see alpha used as an angle, particularly in trig.
The next symbol is a beta. which can also be an angle in trigonometry. Next we have the Greek symbol gamma.
After that you have the symbol delta which can be represented in any of these two forms. The first one is the lowercase Greek alphabet of delta, the second one the triangle is the uppercase. The triangle you'll see this in calculus this means change.
So for example, delta x, that's the change in x, or delta y, the change in y. The next Greek symbol that you'll typically encounter is epsilon. In physics, this would represent the dielectric constant within a capacitor.
Next, we have zeta. In physics, this would be impedance, particularly in an RLC circuit. The next Greek symbol is theta.
Now, I'm sure you've encountered this symbol if you've taken a trigonometry or pre-calculus. So this would represent the angle in trig. The next symbol is kappa.
And this one, you've seen it in chemistry or physics, this is lambda. In chemistry, this would be the wavelength of a wave. And the same is true in physics.
Next, we have this symbol, mu. And you've seen this in terms of units. Think of micrometers or micrograms.
Next, we have the Greek symbol nu, which looks like a V. This represents frequency when dealing with waves. The next one is pi, which is typically encountered in math and geometry. This is the value 3.14159, with some other numbers added to that as well.
In physics, we have the Greek symbol rho. Which, in electricity topics, this would be resistivity, but in more classical physics, like let's say fluid mechanics, you might see this as density. Now, since I'm running out of space, I'm going to clear away a few things.
Now, the next symbol is sigma, which you'll see it in two forms. That's the lower case of sigma. and this is the uppercase version of sigma. So the lowercase sigma, this will typically correspond to an angle, just as theta would represent an angle in trigonometry. The uppercase version of sigma, this is, you'll see this in math, this represents summation or sum.
So for instance, let's say if we have the sigma of x squared starting from 1 to 5, this would be 1 squared plus 2 squared plus 3 squared plus 4 squared plus 5 squared. So the capitalized version of sigma represents sum. Next, we have the Greek symbol tau.
And you'll see this in physics when you're dealing with the time constant of RC circuits. Tau is equal to RC. The next Greek symbol that we have is phi, which is another type of angle.
Next we have omega. This symbol typically corresponds to angular frequency. Omega is equal to 2 pi f 2 pi times the regular frequency Another unit of or symbol of Omega is this one this is the uppercase version of Omega and You'll see this symbol when dealing with electrical circuits So this symbol is the unit of resistance which is measured in ohms.
So those are some common Greek alphabet symbols that you encounter when taking chemistry, physics, or certain courses in math. So that's it for this video. Hopefully you found it to be educational.
