To find the derivative of the function (1/8cos(x) - 3tan(x)), we need to use the chain rule and the derivative rules for cosine and tangent functions.
Let's break down the original function into two separate functions: f(x) = 1/8cos(x) and g(x) = 3tan(x).
The derivative of f(x) = 1/8cos(x) with respect to x is:f'(x) = -1/8sin(x)
The derivative of g(x) = 3tan(x) with respect to x is:g'(x) = 3sec^2(x)
Now, we apply the chain rule to find the derivative of the original function:
(1/8cos(x) - 3tan(x))' = f'(x) - g'(x)= (-1/8sin(x)) - (3sec^2(x))= -1/8sin(x) - 3sec^2(x)
Therefore, the derivative of the function (1/8cos(x) - 3tan(x)) is -1/8sin(x) - 3sec^2(x).

Therefore, the derivative of the function (1/8cos(x) - 3tan(x)) is -1/8sin(x) - 3sec^2(x).
