Explain to me:
Why the 2πf came in front?
I lost touch and sort of forgot.

The basic concept of differentiation of trigonometric functions involves finding the rate of change of a trigonometric function at a given point. This is done by taking the derivative of the function, which represents the slope of the tangent line at that point.
To differentiate a sine function, you can use the basic derivative rule: d/dx(sin(x)) = cos(x). This means that the derivative of the sine function is equal to the cosine function.
Yes, you can differentiate a cosine function using the same derivative rule as the sine function: d/dx(cos(x)) = -sin(x). This means that the derivative of the cosine function is equal to the negative sine function.
The derivative of the tangent function is found by using the quotient rule: d/dx(tan(x)) = sec^2(x). This means that the derivative of the tangent function is equal to the secant squared function.
Differentiation of trigonometric functions is used in many real-world applications, such as physics, engineering, and economics. For example, it can be used to calculate the velocity and acceleration of a moving object or to analyze the behavior of a stock market trend. It is also used in signal processing and in the design of electronic circuits.
