Full solution

Q. Find ddx(sin7x) \frac{d}{d x}(\sin 7 x) \newlineAnswer:
  1. Identify Chain Rule: We need to find the derivative of sin(7x)\sin(7x) with respect to xx. According to the chain rule, the derivative of sin(u)\sin(u) with respect to xx is cos(u)\cos(u) times the derivative of uu with respect to xx, where uu is a function of xx. In this case, u=7xu = 7x.
  2. Find Derivative of u: First, we find the derivative of u=7xu = 7x with respect to xx. The derivative of 7x7x with respect to xx is 77, because the derivative of xx is 11 and 77 is a constant.
  3. Apply Chain Rule: Now, we apply the chain rule. The derivative of sin(7x)\sin(7x) with respect to xx is cos(7x)\cos(7x) times the derivative of 7x7x with respect to xx, which we found to be 77.
  4. Final Derivative: Therefore, the derivative of sin(7x)\sin(7x) with respect to xx is 7cos(7x)7 \cdot \cos(7x).
