3 - - 3 - 2*sin(x - 1) x
3/x - 3 - 2*sin(x - 1)
Differentiate term by term:
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The derivative of the constant is zero.
The result is:
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
The result of the chain rule is:
So, the result is:
The result is:
Now simplify:
The answer is:
3 - -- - 2*cos(x - 1) 2 x
