Question

Find the angle(s) of intersection between the equations f (x) = x 2 + 2x + 1 and g(x) = 1.

Answer 1

Multiple Answers can be selected.

18.4 degrees
26.6 degrees
63.4 degrees
71.6 degrees

Answer 2

63.4 degrees

Answer 3

is that the only answer?

Answer 4

intersection of curves can be found by solving(f(x) = g(x)):- x^2+2x+1 = 1. Which gives x=0,-2.
The derivative of f(x) = 2x + 2, which comes 2 and -2 at x=0 and at x= -2 respectively. The other curve has zero slope, so the answer will be arctan(mod(2)) and arctan(mod(-2)), which is nearly 63.4 degrees.

Answer 5

yes
