Which numbers if any, are NOT in the domain of f(x)=sin(x)/2+cos(x) ??
To determine which numbers are not in the domain of the function f(x) = sin(x)/2 + cos(x), we need to identify any values of x that would result in division by zero or undefined values.
In this particular function, there are no division operations that could result in division by zero. However, we need to consider if there are any values of x that could make the cosine function undefined.
The cosine function is defined for all real numbers, so it does not pose any issues for the domain. Therefore, there are no numbers that are not in the domain of the function f(x) = sin(x)/2 + cos(x). The domain of this function is all real numbers, or (-∞, +∞).
