A Little Thought

Finding Sine

First convert degrees to radians.

1/57.2958 x/y

Where y is the Degree and x is the Variable of the Radian you're trying to figure. Cross multiply.

For Sine

1/.9069 x/y

And here is the base number for one radian. So you would put the radian, converted from degrees, into the x, and the y will be the actual fraction the degree is equal to.

So one radian is equal to .9069.

Doesn't work. Because it's two different base number systems.

But converting Degrees to Radians does. Since it converts the Base Pi to the Base 180.

Basically, sine and cosine has to be memorized, or physically constructed to work.

Also, the arc of the curve, on Sine and Cosine, makes the result different, as it only forms to the basis of a Right Triangle's Geometry from a radius. Meaning, it cannot be derived this simply.
