IMPORTANT - requires printpts stored in the same folder as your current folder or in the “library” folder (see the Variable Manager).
intpts(f, g, l, u)
- f is an expression in terms of x
- g is an expression in terms of x
- l is the lower boundary of x (l should not be in terms of unknown variables, and should be -∞ if either f or g contains other unknown variables besides x)
- u is the upper boundary of x (u should not be in terms of unknown variables, and should be ∞ if either f or g contains other unknown variables besides x)
Returns a list of coordinates of points of intersection of f and g.
Example
Find the coordinates of the points of intersection of the graphs of \((x-1)^3 (x+2)^3\) and \((x-1)^2 (x+2)^3\). (2019 NHT Methods Exam 2 Section B Question 1a)
