Apply Differentiation Rules: To find the derivative of the function 3y2−sin(y) with respect to y, we will apply the basic differentiation rules. The power rule for the term 3y2 and the derivative of the sine function for the term −sin(y).
Differentiate 3y2: Differentiate 3y2 with respect to y. According to the power rule, the derivative of yn with respect to y is n⋅y(n−1). Therefore, the derivative of 3y2 is 2⋅3⋅y(2−1)=6y.
Differentiate −sin(y): Differentiate −sin(y) with respect to y. The derivative of sin(y) with respect to y is cos(y), so the derivative of −sin(y) is −cos(y).
Combine Derivatives: Combine the derivatives of the two terms to get the derivative of the entire function. The derivative of 3y2−sin(y) with respect to y is 6y−cos(y).
