sin(x - y) sin(x + y) = [sin(x) - sin(y)] [sin(x) + sin(y)]

Start with a simple trig ratio:

pesky

cos x
-----
sec x

Cancel the x's:
cos
---
sec

Cancel the c's:
os
--
se

Cancel the s's:
o
-
e

And since 0 over anything is just 0, our final answer is:
0.

The letter 'o' is not a number. :D

However, since sec X = 1 / cos X, cos X / sec X = cos X / ( 1 / cos X ), meaning that cos X / sec X = cos X / ( 1 / cos X ), which equals cos X * cos X, which equals ( cos X ) ^ 2.

But, you can be saved by zero.

That certainly sums up the product.

I think I am behind the curve on this one.

[DM Livgin]

Huh, it is true. Why is it true? No. Nevermind.

[Sharoth]

i am glad that this is not an imaginary thread.

[Existential Crisis C. Yesterday]

You sure about that?

It has its ups and downs, its positives and its negatives. However, it involves pi, which is always a good thing (French Silk is my favorite).

However, if you get Sine and Cosine together, it just devolves into circular logic.

We could switch to talking about Calculus, but that's so derivative.

Wait, if you Sine a ball, does it become a curve ball?

It's a sine!
