Find the derivative of `{(3)/((x)^(1/3)) - 5/(cosx) +6/(sinx ) - (2tanx )/(sec x) + 7}`.

Explanation

To find the derivative of the function

\[ f(x) = \frac{3}{x^{1/3}} - \frac{5}{\cos x} + \frac{6}{\sin x} - \frac{2 \tan x}{\sec x} + 7, \]

we will simplify the function first and then differentiate it step by step.
