WebDerivative of the Cosine Squared Function In this tutorial we shall discuss the derivative of the cosine squared function and its related examples. It can be proved using the definition of differentiation. We have a function of the form y = f ( x) = cos 2 x By the definition of differentiation we have
Web6 rows · The derivative of cos square x is equal to the negative of the trigonometric function sin2x. ... WebSep 7, 2024 · The inverse of g(x) = x + 2 x is f(x) = 2 x − 1. We will use Equation 3.7.2 and begin by finding f′ (x). Thus, f′ (g(x)) = − 2 (g(x) − 1)2 = − 2 (x + 2 x − 1)2 = − x2 2. g′ (x) = 1 f′ (g(x)) = − 2 x2. We can verify that this is the correct derivative by applying the quotient rule to g(x) to obtain. g′ (x) = − 2 x2.
