Simplify the expression for fx by writing it in terms of sinx and cosx and then find f x


Introduction


Differentiation is a process of finding a function that best fits a set of data points. In calculus, a mathematician finds the best linear approximation to a set of data points. The slope of this line is the instantaneous rate of change, or derivative, of the function at that point. This process can be applied to any set of data, including trigonometric functions.

The function f(x) = sin(x) can be simplified by writing it in terms of sin(x) and cos(x). This will allow us to find the derivative of f(x) at any point using the definition of derivatives.

f'(x) = cos(x)sinx + sin(x)cosx

f'(pi/2) = 0 + 1*1

f'(pi/2) = 1

What is f(x)?

In mathematics, f(x) is often used to denote the function that assigns to each x in the domain of f a real value f(x). In particular, f(x) may be a polynomial, a rational function, a trigonometric function, or some other mathematical function. The identification of f with its graph is sometimes called “the graph of the function f”.

How to simplify f(x)?

We can simplify the expression for f(x) by writing it in terms of sin(x) and cos(x). The simplified expression is:

f(x) = sin(x) + cos(x)

To find f(x), we substitute the values of sin(x) and cos(x) into the equation. For example, if x = 0, then

f(0) = sin(0) + cos(0)
f(0) = 0 + 1
f(0) = 1

How to find f(x)?

f(x)= 3sinx+ 4cosx – (3sinx+ 4cosx)
