\right\]\ =\ -\sin(2x)\,\cdot\,\frac{d}{dx}\left\[2x\right\]\ =\ -2\sin(2x))
\ =\ -2\sin(2(2.4)))
The result of the calculation is the slope of the tangent, and the inverse tangent of that value is the elevation.

Find the slope and the elevation of the tangent to the graph of y=cos 2x where x=2.4 radians.
--------------
y = cos(2x)
y' = -2sin(2x)
Slope = y'(2.4) = -2sin(4.8) =~ 1.99233
-----------
If by elevation you mean the y value:
y(2.4) = cos(4.8) =~ 0.0875
