Final Answer
Step-by-step solution
Problem to solve:
Solving method
The derivative of the tangent of a function is equal to secant squared of that function times the derivative of that function, in other words, if ${f(x) = tan(x)}$, then ${f'(x) = sec^2(x)\cdot D_x(x)}$
The derivative of a sum of two functions is the sum of the derivatives of each function
$x+0=x$, where $x$ is any expression
The derivative of the constant function ($1$) is equal to zero
Any expression multiplied by $1$ is equal to itself
The derivative of the linear function is equal to $1$
