Learn how to solve differential calculus problems step by step online. Find the derivative of ab(((sin(s45)+cos(45))1)/(x-1)-(x^2-2x+1)(cos(45)-sin(45))). Simplifying. 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}}. Simplify the product -(\sin\left(s45\right)+\frac{\sqrt{2}}{2}). The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function.
