$2\frac{d}{dx}\left(\tan\left(2x\right)\right)$

Learn how to solve differential calculus problems step by step online. Find the derivative of 2tan(2x). The derivative of a function multiplied by a constant (2) is equal to the constant times the derivative of the function. 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 the linear function times a constant, is equal to the constant.
