what is the derivative of x - sin x
Solution
It is 1-cosx. The power of x is reduced from 1 to 0 (x raised to power 0 is 1) and the derivative of -sinx is -cosx. I guess the function increases when the derivative is positive and it decreases when the derivative is negative. You could plug-in different values of x into the answer for the function\'s derivaative to find those intervals.
