x - sin(x)
Differentiate x−sin(x)x - \sin{\left(x \right)}x−sin(x) term by term:
Apply the power rule: xxx goes to 111
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of sine is cosine:
So, the result is: −cos(x)- \cos{\left(x \right)}−cos(x)
The result is: 1−cos(x)1 - \cos{\left(x \right)}1−cos(x)
The answer is:
1 - cos(x)
sin(x)
cos(x)
