[ f'(x) = 3x^2 \sin x + x^3 \cos x ]
This problem tests the understanding of differentiation rules and their application.
Algebra: Solving a Quadratic Equation
Problem: Solve ( 2x^2 - 5x + 3 = 0 ).
Approach: Use the quadratic formula ( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ).
Calculate the discriminant:
[ \Delta = (-5)^2 - 4 \times 2 \times 3 = 25 - 24 = 1 ]
Then,
[ x = \frac{5 \pm 1}{4} ]
So,
[ x = \frac{6}{4} = 1.5 \quad \text{or} \quad x = \frac{4}{4} = 1 ]
This reinforces solving standard algebraic equations.
Coordinate Geometry: Equation of a Circle
Problem: Find the equation of a circle with center at (2, -3) and radius 5.
Approach: Use the standard form of a circle’s equation:
[ (x - h)^2 + (y - k)^2 = r^2 ]
Substitute ( h = 2 ), ( k = -3 ), and ( r = 5 ):
