Q. Find ddv(3v33sinv) \frac{d}{d v}\left(3 v^{3}-3 \sin v\right) \newlineAnswer:
  1. Differentiate 3v33v^3: Differentiate the term 3v33v^3 with respect to vv. To differentiate 3v33v^3, we use the power rule which states that the derivative of vnv^n with respect to vv is nv(n1)n\cdot v^{(n-1)}. Therefore, the derivative of 3v33v^3 is 3(3)v(31)=9v23\cdot(3)\cdot v^{(3-1)} = 9v^2.
  2. Differentiate 3sin(v)-3\sin(v): Differentiate the term 3sin(v)-3\sin(v) with respect to vv. The derivative of sin(v)\sin(v) with respect to vv is cos(v)\cos(v). Therefore, the derivative of 3sin(v)-3\sin(v) is 3cos(v)-3\cos(v).
  3. Combine derivatives: Combine the derivatives from Step 11 and Step 22.\newlineThe derivative of the entire function 3v33sin(v)3v^3 - 3\sin(v) with respect to vv is the sum of the derivatives of its terms, which is 9v23cos(v)9v^2 - 3\cos(v).
