Q. For the following equation, find dydx \frac{d y}{d x} .\newliney=3x5+9x47x3+3x y=3 x^{5}+9 x^{4}-7 x^{3}+3 x \newlineAnswer: dydx= \frac{d y}{d x}=
  1. Apply Power Rule: To find the derivative of the function yy with respect to xx, we will apply the power rule to each term individually. The power rule states that the derivative of xnx^n with respect to xx is nx(n1)n\cdot x^{(n-1)}.
  2. Derivative of 3x53x^5: First, we find the derivative of the term 3x53x^{5}. Using the power rule, we get:\newlinedydx(3x5)=3×5×x51=15x4\frac{dy}{dx}(3x^{5}) = 3 \times 5 \times x^{5-1} = 15x^{4}.
  3. Derivative of 9x49x^4: Next, we find the derivative of the term 9x49x^{4}. Using the power rule, we get:\newlinedydx(9x4)=94x41=36x3\frac{dy}{dx}(9x^{4}) = 9 \cdot 4 \cdot x^{4-1} = 36x^{3}.
  4. Derivative of 7x3-7x^3: Then, we find the derivative of the term 7x3-7x^{3}. Using the power rule, we get:\newlinedydx(7x3)=7×3×x31=21x2\frac{dy}{dx}(-7x^{3}) = -7 \times 3 \times x^{3-1} = -21x^{2}.
  5. Derivative of 3x3x: Finally, we find the derivative of the term 3x3x. Since this is a linear term, its derivative is simply the coefficient of xx: \newline rac{dy}{dx}(3x) = 3.
  6. Combine Derivatives: Now, we combine all the derivatives we found to get the derivative of the entire function yy: dydx=15x4+36x321x2+3\frac{dy}{dx} = 15x^{4} + 36x^{3} - 21x^{2} + 3.
