Answer:

[tex]\displaystyle y' = 6 \sec^2 (3x) \tan (3x)[/tex]

General Formulas and Concepts:

Calculus

Differentiation

  • Derivatives
  • Derivative Notation

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

Basic Power Rule:

  1. f(x) = cxⁿ
  2. f’(x) = c·nxⁿ⁻¹

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

Step-by-step explanation:

Step 1: Define

Identify

[tex]\displaystyle y = \sec^2 (3x)[/tex]

Step 2: Differentiate

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