Derivative Property [Multiplied Constant]:                                                           \(\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)\)

Basic Power Rule:

  1. f(x) = cxⁿ
  2. f’(x) = c·nxⁿ⁻¹

Derivative Rule [Chain Rule]:                                                                                \(\displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)\)

Step-by-step explanation:

Step 1: Define

Identify

\(\displaystyle y = \sec^2 (3x)\)

Step 2: Differentiate

  1. Basic Power Rule [Derivative Rule - Chain Rule]:                                       \(\displaystyle y' = 2\sec (3x) \cdot [\sec (3x)]'\)
  2. Trigonometric Differentiation [Derivative Rule - Chain Rule]:                   \(\displaystyle y' = 2\sec^2 (3x) \tan (3x) (3x)'\)
  3. Basic Power Rule [Derivative Property - Multiplied Constant]:                 \(\displaystyle y' = 6 \sec^2 (3x) \tan (3x)\)
