Find any intervals where the function f(x)=−(5x+5sin(x)),0≤x≤2π is increasing/decreasing.
You guys are awesome. Thanks!
is x in radians or degrees?
If x is in radians, then f(x) is decreasing from [0, π) and at (π, 2π], or 0≤x<π and π<x≤2π.
I think radians. If it's not then I can just do any conversions to degrees.
In degrees, it is just a constantly decreasing linear function, so x is in radians.
