Differentiating sin2x

Derivative is the rate of change of a function with relation to a variable. Derivatives are critical in the solution of calculus and differential equation problems. In this article, we will use various methods to demonstrate that the derivative of sin differentiating sin2x is 2 cos 2x. Because sin 2x involves a double angle, differentiating sin2x, so does its derivative.

Before going to find the derivative of sin 2x, let us recall a few facts about sin 2x. Since sin 2x involves double angle, its derivative also involves the double angle. In this article, we are going to prove that the differentiation of sin 2x is 2 cos 2x using various methods. Note that sin 2x and sin 2 x are different from each other. In this article, we are going to see the difference between the derivatives of sin 2x and sin square x. The derivative of sin 2x is 2 cos 2x.

Note that in this post we will be looking at differentiating sin 2 x which is not the same as differentiating sin 2x. Here is our post dealing with how to differentiate sin 2x. The first method is by using the product rule for derivatives since sin 2 x can be written as sin x. The product rule for differentiation states that the derivative of f x. The Product Rule: For two differentiable functions f x and g x. The chain rule is useful for finding the derivative of a function which could have been differentiated had it been in x, but it is in the form of another expression which could also be differentiated if it stood on its own. Although the expression sin 2 x contains no parenthesis, we can still view it as a composite function a function of a function. Now the function is in the form of x 2 , except it does not have x as the base, instead it has another function of x sin x as the base. The Chain Rule: For two differentiable functions f x and g x. Just be aware that not all of the forms below are mathematically correct. Interestingly, the second derivative of sin 2 x is equal to the first derivative of sin 2x. View all posts by DerivativeIt. The second method is by using the chain rule for differentiation.

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. The derivative of the sine function is the cosine and the derivative of the cosine function is the negative sine.
