Cosine of minus theta is equal to cosine of theta.

Sine of 2x is equal to 2 sine of x cosine of x.

We have cosine Well we have sine of x times cosine of 2x.

Sin of x over cosine of x.

Well, it's sine of x.

Well the derivative of sine of x is just cosine of x. So it's going to be negative 2 cosine of x.

One was from Jeb Bradley.

Times cosine of minus mu x plus i sine of minus mu x.

So this is sin squared x over cosine squared x, which is actually equal to what's sin over cosine?

So this is equal to the integral from 0 to t, of sine of t, times the cosine squared of tau d tau minus the integral from 0 to t of cosine of t times sine of tau cosine of tau d tau.

So the convolution of sine of t with cosine of t is 1 2t sine of t.

Cosine of x divided cosine of x is 1.

Cosine of 2 pi is the same thing as cosine of 0.

Cosine of minus t and 2 sine of minus t.

Hiya, Gabe.

Gabe.

Hey, Gabe!

If we said u is equal to sine of tau, then du d tau is equal to the cosine of tau, just the derivative of sine.

So x sub 2, x sub 2 is going to be equal to its going to be equal to the cosine, the cos(2pi 3) i sin(2pi 3).

And the antiderivative of cosine of x is sine of x, which is just as complicated.

He took a key from his coat pocket.

Transform of sine of 2t.

This is just what sine, cosine, and tangent are.

So this is cosine of x divided by cosine of x.

Laplace Transform of sine of t plus sine of t.

When air rises, moist air cools at a lower rate than dry air.

This sine times this sine is sine squared of t cosine of t.

An air purifier is a device which removes contaminants from the air.

Derivative of sin of x is cosine of x, times the second term.

Well derivative of cosine x is minus sin of x.

So it becomes 2 sine of x cosine of x.

The derivative of cosine of x is minus sin of x.
