Full solution

Q. Find ddx(3sinx) \frac{d}{d x}(-3 \sin x) \newlineAnswer:
  1. Identify Function: Identify the function to differentiate.\newlineWe need to find the derivative of the function f(x)=3sin(x)f(x) = -3\sin(x) with respect to xx.
  2. Apply Derivative Rule: Apply the derivative rule for sine function.\newlineThe derivative of sin(x)\sin(x) with respect to xx is cos(x)\cos(x). Therefore, the derivative of 3sin(x)-3\sin(x) is 3-3 times the derivative of sin(x)\sin(x).
  3. Multiply by Constant: Multiply the derivative of sin(x)\sin(x) by the constant.\newlineSince the derivative of sin(x)\sin(x) is cos(x)\cos(x), we multiply this by the constant 3-3 to get the derivative of the entire function.\newlineddx(3sin(x))=3×ddx(sin(x))=3×cos(x)\frac{d}{dx}(-3\sin(x)) = -3 \times \frac{d}{dx}(\sin(x)) = -3 \times \cos(x)
