Identify Function: Identify the function to differentiate.We are given the function f(x)=−sin(x)+1 and we need to find its derivative with respect to x.
Apply Derivative Rules: Apply the derivative rules.The derivative of −sin(x) with respect to x is −cos(x), because the derivative of sin(x) is cos(x) and we must also consider the negative sign in front of sin(x).The derivative of a constant, such as +1, is 0.
Combine Derivatives: Combine the derivatives.The derivative of the entire function f(x)=−sin(x)+1 is the sum of the derivatives of its parts, which is −cos(x)+0.
Simplify Result: Simplify the result.Since adding 0 does not change the value, the final derivative is simply −cos(x).
