$\frac{d}{dx}\left(\frac{\left(1-\sin\left(x\right)+\cos\left(x\right)\right)^2}{2\left(1+\cos\left(x\right)\right)}\right)+\frac{d}{dx}\left(\sin\left(x\right)\right)$
Learn how to solve problems step by step online. Find the derivative of ((1-sin(x)cos(x))^2)/(2(1+cos(x)))+sin(x). The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of the sine of a function is equal to the cosine of that function times the derivative of that function, in other words, if {f(x) = \sin(x)}, then {f'(x) = \cos(x)\cdot D_x(x)}. Apply the quotient rule for differentiation, which states that if f(x) and g(x) are functions and h(x) is the function defined by {\displaystyle h(x) = \frac{f(x)}{g(x)}}, where {g(x) \neq 0}, then {\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}. The power of a product is equal to the product of it's factors raised to the same power.
