what is the derivative of y=2 sin x cos x ? Implicit Differentiation :Consider a function f(x) its derivative with respect to x can be found by ddxf(x)=f′(x) For a function f(y) its derivative with respect to x gives ddxf(y)=f′(y)dydx Derivative of ddxf(g(x))=f′(g(...
The derivatives of sine and cosine are given by ddx sin x = cos x and ddx cos x= − sin x Other than this, it is important to know the quotient rule, a method to differentiate functions that can be written as a fraction. If f(x) = g(x)h(x) and h(x) ≠...
f(x) = sin(3x2) When applying the chain rule: f '(x) = cos(3x2) ⋅ [3x2]' = cos(3x2) ⋅ 6x Second derivative test When the first derivative of a function is zero at point x0. f'(x0) = 0 Then the second derivative at point x0, f''(x0), can indicate the type...
