Techniques of Differentiation - Derivatives of Trigonometric Functions

Find the derivatives of the following functions with respect to \(x\):

  1. \(y = \ln \left( \frac{\tan^{3}(1 - e^{x})}{\ln x^{3}} \right)\)
  2. \(y = \ln \left( \frac{x^{5}}{\sin^{2}x} \right)\)
  3. \(y = \ln \left( \frac{\ln x^{3}}{\tan x} \right)\)
