MA522, Fall 2021, HOMEWORK 5: (due Thur Nov 11, 11:55pm, by email or upload on Moodle; you can send/upload cell phone photos of your handwritten solution). Problem 1 is Problem 6.33 [of the Exercises for Section 6]: intersection of 2 planar curves. It may help to use Maple to compute the resultants in the main variable a (projection to b coordinate) or the main variable b (projection to the a coordinate). The curves are b - a^3 + 7a - 5 = 0, 20 a^2 - 5 a b - 4 b^2 + 35 a + 35 b - 21 = 0 in the variables a, b. ======================================================================
