Apply Power Rule: To find the derivative of the function 3z5−4sin(z) with respect to z, we will apply the power rule to the term 3z5 and the derivative of the sine function to the term −4sin(z).
Derivative of 3z5: The power rule states that the derivative of zn with respect to z is n∗z(n−1). Applying this to 3z5, we get the derivative as 5∗3z(5−1) which simplifies to 15z4.
Derivative of −4sin(z): The derivative of −4sin(z) with respect to z is −4cos(z), because the derivative of sin(z) is cos(z), and we multiply by the constant −4.
Combine Derivatives: Combining the derivatives of both terms, we get the derivative of the entire function 3z5−4sin(z) with respect to z as 15z4−4cos(z).
