Derivative of negative cosine

WebJan 28, 2024 · Prove that the derivative of sine is cosine. In an informal exam tonight, my professor asked me to demonstrate that for using the definition of the derivative, . And here I managed to stump him. In order to prove that this equals , we need to demonstrate that and that . You can't simply plug in because that would lead to an indeterminate form. WebThe nice thing about trigonometric functions is that taking the derivative shifts the curve 90 degrees to the left. Sine and cosine each have 360 degree symmetry, and 180 degree reverse symmetry, so taking two derivatives always gets you the negative of the original function, and taking four gets you the original function back.

WebDec 23, 2014 · Dec 23, 2014. The previous answer contains mistakes. Here is the correct derivation. First of all, the minus sign in front of a function f (x) = − sin(x), when taking a derivative, would change the sign of a derivative of a function f (x) = sin(x) to an opposite. This is an easy theorem in the theory of limits: limit of a constant multiplied ... WebThe derivative of cos inverse x is given by -1/√ (1 - x 2 ), where -1 < x < 1, which is negative of the derivative of sin inverse x. Mathematically, the derivative of arccos is written as d (cos -1 x)/dx = d (arccos)/dx = -1/√ (1 - x 2 ). The derivative of cos inverse can be determined by implicit differentiation.
