Explanation / Answer

Solution 10:

when fzero function is deployed on
F(x) = sin(2x) - cos(3x)
The brackets that will find roots of F(x) at x = 0.3142 will be

Option B (0,1)
Option C (-2,3)

Solution 11:
roots command is used to find roots of equation
coefficient of x^4, x^3, x^2, x^1 and x^0 will be 2, -7, 0, 5 and -1.

Answer will be:
Option A roots([2 -7 0 5 -1])
