WebSep 7, 2024 · We can find the derivatives of sinx and cosx by using the definition of derivative and the limit formulas found earlier. The results are. d dx (sinx) = cosx and d dx (cosx) = − sinx. With these two formulas, we can determine the derivatives of all six … WebThe derivative of arccos x is given by -1/√ (1-x 2) where -1 < x < 1. It is also called the derivative of cos inverse x, that is, the derivative of the inverse cosine function. Derivatives of all inverse trigonometric functions can be calculated using the method of implicit differentiation.
