Apply Power Rule: To find the derivative of the function 4v5−cos(v) with respect to v, we need to apply the power rule to the term 4v5 and the derivative of the cosine function to the term −cos(v).
Derivative of Cosine: The power rule states that the derivative of vn with respect to v is n∗v(n−1). Applying this to 4v5, we get 5∗4v4 or 20v4.
Combine Derivatives: The derivative of −cos(v) with respect to v is sin(v), but since we have a negative sign, it becomes −sin(v).
Check for Errors: Combining the derivatives of both terms, we get the derivative of the entire function: 20v4−sin(v).
Check for Errors: Combining the derivatives of both terms, we get the derivative of the entire function: 20v4−sin(v).We check for any mathematical errors in the differentiation process. The power rule was applied correctly, and the derivative of the cosine function was also correctly determined.
