As \(x \to 0\), numerator \(\sin 3x \to 0\), and denominator \(5x \to 0\). This is an indeterminate form \(\frac{0}{0}\), suitable for L'Hôpital's Rule. Step 2: Apply L'Hôpital's Rule. Differentiate numerator and denominator separately: \[ \lim_{x \to 0} \frac{\frac{d}{dx} \sin 3x}{\frac{d}{dx} 5x} = \lim_{x \to 0} \frac{3 \cos 3x}{5} \] Step 3: Substitute \(x = 0\): \[ \frac{3 \cos 0}{5} = \frac{3 \times 1}{5} = \frac{3}{5} \] Answer: \[ \boxed{\frac{3}{5}} \] --- Problem 2: Differentiation Using Chain Rule Question: Find \( \frac{dy}{dx} \) if \( y = \sqrt{4x^2 + 1} \). Solution: Step 1: Rewrite \( y \) for easier differentiation: \[ y = (4x^2 + 1)^{1/2} \] Step 2: Apply the Chain Rule: \[ \frac{dy}{dx} = \frac{1}{2} (4x^2 + 1)^{-1/2} \times \frac{d}{dx} (4x^2 + 1) \] Step 3: Differentiate inside the parentheses: \[ \frac{d}{dx} (4x^2 + 1) = 8x \] Step 4: Combine: \[ \frac{dy}{dx} = \frac{1}{2} \times (4x^2 + 1)^{-1/2} \times 8x = \frac{8x}{2 \sqrt{4x^2 + 1}} = \frac{4x}{\sqrt{4x^2 + 1}} \] Answer: \[ \boxed{\frac{dy}{dx} = \frac{4x}{\sqrt{4x^2 + 1}}} \] --- Problem 3: Maxima and 2 Minima Using the First Derivative Test Question: Determine the local maxima and minima of \(f(x) = x^3 - 6x^2 + 9x + 2\). Solution: Step 1: Find \(f'(x)\): \[ f'(x) = 3x^2 - 12x + 9 \] Step 2: Find critical points by setting \(f'(x) = 0\): \[ 3x^2 - 12x + 9 = 0 \] Divide through by 3: \[ x^2 - 4x + 3 = 0 \] Factor: \[ (x - 1)(x - 3) = 0 \] Critical points at \(x=1\) and \(x=3\). Step 3: Use the First Derivative Test to classify critical points. - For \(x < 1\), pick \(x=0\): \[ f'(0) = 3(0)^2 - 12(0) + 9 = 9 > 0 \] - Between 1 and 3, pick \(x=2\): \[ f'(2) = 3(4) - 12(2) + 9 = 12 - 24 + 9 = -3 < 0 \] - For \(x > 3\), pick \(x=4\): \[ f'(4) = 3(16) - 12(4) + 9 = 48 - 48 + 9 = 9 > 0 \] Step 4: Analyze sign changes: - At \(x=1\): \(f'\) changes from positive to negative → local maximum at \(x=1\). - At \(x=3\): \(f'\) changes from negative to positive → local minimum at \(x=3\). Step 5: Find the function values at critical points: - \(f(1) = 1^3 - 6(1)^2 + 9(1) + 2 = 1 - 6 + 9 + 2 = 6\) - \(f(3) = 27 - 54 + 27 + 2 = 2\) Answer: - Local maximum at \(\boxed{x=1}\), \(f(1)=6\) - Local minimum at \(\boxed{x=3}\), \(f(3)=2\) --- Problem 4: Computing Definite Integrals Question: Calculate \(\int_{0}^{2} (3x^2 + 4) \, dx\). Solution: Step 1: Find the antiderivative: \[ \int (3x^2 + 4) dx = x^3 + 4x + C \] Step 2: Evaluate from 0 to 2: \[ \left[ x^3 + 4x \right]_0^2 = (2)^3 + 4(2) - (0)^3 - 4(0) = 8 + 8 - 0 - 0 = 16 \] Answer: \[ \boxed{16} \] --- Strategies for Effective Preparation Using Sample Exams Step-by-step Approach 1.

Recall that: \[ \lim_{x \to 0} \frac{\sin x}{x} = 1 \] Applying this, we rewrite the limit: \[ \lim_{x \to 0} \frac{\sin 3x}{5x} = \frac{1}{5} \lim_{x \to 0} \frac{\sin 3x}{3x} \times 3 \] But more straightforwardly: \[ \lim_{x \to 0} \frac{\sin 3x}{5x} = \frac{1}{5} \times \lim_{x \to 0} \frac{\sin 3x}{3x} \times 3 \] Alternatively, simply: \[ \lim_{x \to 0} \frac{\sin 3x}{5x} = \frac{1}{5} \times \lim_{x \to 0} \frac{\sin 3x}{3x} \times 3 \] Since: \[ \lim_{x \to 0} \frac{\sin 3x}{3x} = 1 \] We get: \[ \frac{1}{5} \times 1 \times 3 = \frac{3}{5} \] Answer: \(\boxed{\frac{3}{5}}\) Insight: Leveraging the standard limit and adjusting for the coefficients simplifies the process. --- Question 2: Find the Derivative of the Function Given: \[ f(x) = x^2 \ln x, \quad x > 0 \] Find: \(f'(x)\) Solution: This function is a product of two functions: \(u = x^2\) and \(v = \ln x\). We apply the product rule: \[ f'(x) = u'v + uv' \] Calc Sample Examination Vi And Solution 5 Calculations: - \(u' = 2x\) - \(v' = \frac{1}{x}\) Therefore: \[ f'(x) = 2x \ln x + x^2 \times \frac{1}{x} = 2x \ln x + x \] Answer: \(\boxed{f'(x) = 2x \ln x + x}\) Insight: Recognizing the product structure and applying the product rule efficiently simplifies differentiation. --- Question 3: Compute the Definite Integral Evaluate: \[ \int_0^1 x e^{x} \, dx \] Solution: Use integration by parts: Let: - \(u = x \Rightarrow du = dx\) - \(dv = e^{x} dx \Rightarrow v = e^{x}\) Applying integration by parts: \[ \int x e^{x} dx = uv - \int v du = x e^{x} - \int e^{x} dx \] Calculate: \[ x e^{x} - e^{x} + C \] Evaluate from 0 to 1: \[ [1 \times e^{1} - e^{1}] - [0 \times e^{0} - e^{0}] = (e - e) - (0 - 1) = 0 - (-1) = 1 \] Answer: \(\boxed{1}\) Insight: Integration by parts simplifies the integral, and careful evaluation of limits ensures correctness. --- Advanced Topics and Their Relevance in Sample Examination VI While initial questions focus on fundamental calculus concepts, Sample Examination VI progressively introduces more sophisticated topics, reflecting real-world applications and theoretical depth.
