$-\frac{d}{dx}\left(4x-1\right)\csc\left(4x-1\right)^2$
Learn how to solve problems step by step online. Find the derivative using the product rule d/dx(cot(4x-1)). Taking the derivative of cotangent. The derivative of a sum of two or more functions is the sum of the derivatives of each function. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=. The derivative of the constant function (4) is equal to zero.
