Q. y=x2tan(x)y=x^{2}\tan(x)\newlinedydx=\frac{dy}{dx}=
  1. Identify Function: Identify the function to differentiate.\newlineWe are given the function y=x2tan(x)y = x^2 \cdot \tan(x). We need to find the derivative of this function with respect to xx, which is denoted as dydx\frac{dy}{dx}.
  2. Apply Product Rule: Apply the product rule for differentiation.\newlineThe product rule states that the derivative of a product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function. In this case, our first function is u=x2u = x^2 and our second function is v=tan(x)v = \tan(x).
  3. Differentiate u=x2u = x^2: Differentiate the first function u=x2u = x^2 with respect to xx. The derivative of x2x^2 with respect to xx is 2x2x.
  4. Differentiate v=tan(x)v = \tan(x): Differentiate the second function v=tan(x)v = \tan(x) with respect to xx. The derivative of tan(x)\tan(x) with respect to xx is sec2(x)\sec^2(x).
  5. Apply Product Rule with Derivatives: Apply the product rule using the derivatives from steps 33 and 44.\newlineUsing the product rule, we have:\newlinedydx=dudxv+udvdx\frac{dy}{dx} = \frac{du}{dx} \cdot v + u \cdot \frac{dv}{dx}\newlineSubstituting the derivatives we found, we get:\newlinedydx=2xtan(x)+x2sec2(x)\frac{dy}{dx} = 2x \cdot \tan(x) + x^2 \cdot \sec^2(x)
  6. Simplify Expression: Simplify the expression if possible.\newlineThe expression is already in its simplest form, so we do not need to simplify further.\newlinedydx=2xtan(x)+x2sec2(x)\frac{dy}{dx} = 2x \cdot \tan(x) + x^2 \cdot \sec^2(x)
