Differentiation of x cos x

The differentiation of cos x is the process of evaluating the derivative of cos x or determining the rate of change of cos x with respect to the variable x.

The derivative of xcos x is equal to cosx — xsinx. The function xcos x is the product of x with its cosine. In this article, we will learn how to find the differentiation of xcos x using the following methods:. In the next two sections, we will prove this formula using the product rule of derivatives and the first principle of derivatives, that is, the definition of limits. Hence, the derivative of x cos x is cos x — x sin x obtained using the product rule of derivatives. Also Read:. Derivative of sin3x : The derivative of sin3x is 3cos3x.

One of the most important types of motion in physics is simple harmonic motion, which is associated with such systems as an object with mass oscillating on a spring. Simple harmonic motion can be described by using either sine or cosine functions. In this section we expand our knowledge of derivative formulas to include derivatives of these and other trigonometric functions. We begin with the derivatives of the sine and cosine functions and then use them to obtain formulas for the derivatives of the remaining four trigonometric functions. Being able to calculate the derivatives of the sine and cosine functions will enable us to find the velocity and acceleration of simple harmonic motion. We begin our exploration of the derivative for the sine function by using the formula to make a reasonable guess at its derivative. Indeed, we will show that. If we were to follow the same steps to approximate the derivative of the cosine function, we would find that.
