The sketch graph shows the curve of y = x 5 x 3 . Find: a.
Question:
The sketch graph shows the curve of y = x5 − x3.
Find:
a. The coordinates of the point P where the curve crosses the positive x-axis
b. The equation of the tangent at P
c. The equation of the normal at P.
The tangent at P meets the y-axis at Q and the normal meets the y-axis at R.
d. Find the coordinates of Q and R and hence find the area of triangle PQR.
