Quotient Rule to Find a Tangent Line with a Certain Slope (2.3 #77)
After using the quotient rule to find a formula for slope, we set it to a certain slope to find when the function has that slope. To get the equation of the line, we use the original function to find the y coordinate, and place it in the "Point-Slope" form of a linear equation: y-Y = m (x-X) where the point is (X,Y) and m is the slope.
Finally we use the calculator to check our work both graphically as well as numerically.
