f(pi/2) = -2cos(2pi-3) = -2cos(-3) = 2cos3

f(pi/4) = -2cos(pi-3) = -2cos(-3) = 2cos3.

So the rate of change is<span>on the interval from x = 0 to x = pi over 4 is:</span>

Vinil7 [7]

$\frac{5}{2}x+\frac{1}{4} +\frac{3}{4} x=\frac{1}{8} \\\\\frac{5}{2}(8)x+\frac{1}{4} (8)+\frac{3}{4}(8) x=\frac{1}{8}(8)\\20x+2+6x=1\\20x+6x=1-2\\26x=-1\\\frac{26x}{26} =\frac{-1}{26} \\x=-\frac{1}{26}$
