Q. Given that u=4v2+1 u=4 v^{2}+1 , find ddv(5v54sinu) \frac{d}{d v}\left(5 v^{5}-4 \sin u\right) in terms of only v v .\newlineAnswer:
  1. Find Derivative with Chain Rule: We need to find the derivative of the function with respect to vv. We will use the chain rule for the term involving uu, since uu is a function of vv. The chain rule states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function.
  2. Differentiate 5v55v^{5}: First, let's differentiate the term 5v55v^{5} with respect to vv. The power rule for derivatives tells us that ddv(vn)=nv(n1)\frac{d}{dv}(v^n) = n\cdot v^{(n-1)}, so the derivative of 5v55v^{5} with respect to vv is 55v4=25v45 \cdot 5v^{4} = 25v^{4}.
  3. Differentiate 4sin(u)-4\sin(u): Now, let's differentiate the term 4sin(u)-4\sin(u) with respect to vv. Since uu is a function of vv, we need to use the chain rule. The derivative of 4sin(u)-4\sin(u) with respect to uu is 4cos(u)-4\cos(u), and we need to multiply this by the derivative of uu with respect to vv, which is 4sin(u)-4\sin(u)00.
  4. Apply Chain Rule for uu: The derivative of uu with respect to vv is ddv(4v2+1)=8v\frac{d}{dv}(4v^{2} + 1) = 8v, because the derivative of a constant is 00 and the derivative of 4v24v^{2} is 8v8v using the power rule.
  5. Combine Derivatives: Now, we multiply the derivative of 4sin(u)-4\sin(u) with respect to uu by the derivative of uu with respect to vv to get the full derivative of 4sin(u)-4\sin(u) with respect to vv. This gives us 4cos(u)×8v=32vcos(u)-4\cos(u) \times 8v = -32v\cos(u).
  6. Express in Terms of vv: Finally, we combine the derivatives of both terms to get the full derivative of the function with respect to vv. The derivative of 5v54sin(u)5v^{5} - 4\sin(u) with respect to vv is 25v432vcos(u)25v^{4} - 32v\cos(u).
  7. Express in Terms of v: Finally, we combine the derivatives of both terms to get the full derivative of the function with respect to vv. The derivative of 5v54sin(u)5v^{5} - 4\sin(u) with respect to vv is 25v432vcos(u)25v^{4} - 32v\cos(u).We need to express the derivative in terms of vv only, so we substitute u=4v2+1u = 4v^{2} + 1 into the cosine term. This gives us 32vcos(4v2+1)-32v\cos(4v^{2} + 1).
