1) Line
Maybe your teacher instructor defined trigonometric functions
based on the coordinates of , with .
My 9th grade math teacher defined .
Either way it is for some point
on that blue line that passes through the origin ,
<---> .
Of course that is the slope of the line,
and the slope of is ,
the coefficient of
in the slope-intercept form of the equation of the line.
1) Line
would have to be graphed on a pait if a-b axes.
I would use the usual x-y axes and say that .
Then, the line would be <--> <--> .
If ,
and
since ,
Squaring both sides,
and
