2. Use the subtraction formula for tangent to show that
25x

e = tan-1
x² +264/
Hints:
a. Starting with the equation from #1, take the tangent of both sides.
b. Use the subtraction formula for tangent.
c. Simplify and solve for 0.
3. Use your graphing calculator to graph 0 as a function of x. What value of x maximizes 0? In
which row should you sit? What is the viewing angle (in degrees) in this row?
a. Enter the function in part b into your calculator to graph it (what mode do we use for
graphing?)
b. Adjust the window until you believe you can see the maximum.
c. Go to 2nd > Trace (which is Calc) and choose 4:maximum. Move the cursor so it is on the
left of the max and hit enter, then move the cursor to the right of the max and hit enter
twice. You will see the coordinates of the maximum at the bottom of the screen.
