Using the same process as above, construct a secant-tangent line to the general cosine function g(x)= a•cos(b•x+c) (the light blue curve in figure 11.6). Plot the slope of this line as x varies. Make a conjecture about the derivative of the cosine function.

Because the cosine value on a unit circle is equal to the x coordinate, and any angle terminating in quadrant II intersects with the unit circle at a negative x-coordinate, the cosine value is negative. Because the sine is positive and the cosine is negative, and the tangent equals the sine over the cosine, the tangent will also be negative.

Since we know the sine and cosine values for these angles, it makes sense to relate the tangent and secant values back to the sine and cosine values. Notice this result is consistent with our interpretation of the tangent value as the slope of the line from the origin at the given angle – a line at 45 degrees would indeed have a slope of 1.
