$\frac{d}{dx}\left(\frac{\sin\left(2x\right)-\cos\left(2x\right)}{\sin\left(2x\right)+\cos\left(2x\right)}\right)+\frac{d}{dx}\left(\cos\left(3x\right)\right)$
Learn how to solve problems step by step online. Find the derivative d/dx((sin(2x)-cos(2x))/(sin(2x)+cos(2x))+cos(3x)) using the sum rule. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of the cosine of a function is equal to minus the sine of the function times the derivative of the function, in other words, if f(x) = \cos(x), then f'(x) = -\sin(x)\cdot D_x(x). The derivative of the linear function times a constant, is equal to the constant. The derivative of the linear function is equal to 1.
