That's the secant.
So secant of theta.
One over cosine is secant.
Secant of theta, cosecant theta.
So let me draw that secant line.
It is 6 secant squared theta d theta.
Which is equal to secant squared.
Secant of theta-- it's really for convenience.
So that is the slope of this secant.
So that equals secant squared of theta.
This is just the slope of this secant line.
So it's 6 times secant squared theta d theta.
So the limit as h approaches 0 of my secant slope.
The slope of the secant, let me write that properly.
We learned that the tangent squared of theta plus 1 is equal to the secant of theta.
So this is equal to the secant squared of theta.
So this is secant squared of theta in the denominator.
We know that this right there is secant squared of theta.
The secant of theta-- oops, is equal to the secant squared of theta, sorry.
If I took h to be even a little bit smaller, I would be finding the slope of that secant line.
And then, as h approaches 0, this secant line is going to get closer and closer to the slope of the tangent line.
And then finally the derivative of tan of x is equal to 1 over cosine square of x which you could also write as the secant squared of x.
The secant of theta, instead of being the adjacent over the hypotenuse, would be the hypotenuse over the adjacent, right?
Either way, we're doing a very similar- we're doing the exact same thing- we're finding the- we're taking the s- we're,we're having an expression for the slope of a secant line, and then we're bringing those x values of those points closer and closer together, closer and closer together, so the slopes of those secant lines better and better and better approximate that slope of the tangent line.
