Secant Line Slope and Tangent Line Slope
I have answered these problems already but I am not sure what the correct answers were.
Point P=(3,1/9) lies on 1/x^2
Find slope of secant line PQ for certain values of X:
X=2.5, mSecant=-.097778 <You may want to check the mSecant Val.
X=2.9, mSecant=-.077950 for the values.
b)Estimate the value of the slope of the tagent line at curve P. (use 2.999 and 3.001)
Using the slope from B find equation for tagent line to the curve at (3,1/9)
