Introduction

In calculus, the derivative of a function is a measure of how the function changes as its input changes. In this article, we will explore the derivation of the function 1/tan(2x/1+x^2) with respect to x. This function is a complex trigonometric function that involves the tangent and the quadratic function. We will use various mathematical techniques to simplify and derive the function.

Understanding the Function

The given function is 1/tan(2x/1+x^2). To understand this function, let's break it down into its components. The function involves the tangent of the expression 2x/1+x^2. The tangent function is a trigonometric function that is defined as the ratio of the sine and cosine of an angle. In this case, the angle is 2x/1+x^2.

Derivation of the Function

To derive the function 1/tan(2x/1+x^2) with respect to x, we will use the chain rule and the quotient rule of differentiation. The chain rule states that if we have a composite function of the form f(g(x)), then the derivative of the function is given by f'(g(x)) * g'(x). The quotient rule states that if we have a function of the form f(x)/g(x), then the derivative of the function is given by (f'(x) * g(x) - f(x) * g'(x)) / g(x)^2.

Step 1: Apply the Chain Rule

To derive the function 1/tan(2x/1+x^2), we will first apply the chain rule. The chain rule states that if we have a composite function of the form f(g(x)), then the derivative of the function is given by f'(g(x)) * g'(x). In this case, the composite function is 1/tan(2x/1+x^2). We can rewrite this function as 1/tan(u), where u = 2x/1+x^2.

Step 2: Find the Derivative of the Inner Function

To find the derivative of the inner function u = 2x/1+x^2, we will use the quotient rule. The quotient rule states that if we have a function of the form f(x)/g(x), then the derivative of the function is given by (f'(x) * g(x) - f(x) * g'(x)) / g(x)^2.

Step 3: Apply the Quotient Rule

To find the derivative of the inner function u = 2x/1+x^2, we will apply the quotient rule. The quotient rule states that if we have a function of the form f(x)/g(x), then the derivative of the function is given by (f'(x) * g(x) - f(x) * g'(x)) / g(x)^2.

Step 4: Simplify the Derivative

To simplify the derivative, we will use algebraic manipulation. We will multiply both the numerator and the denominator by the conjugate of the denominator to eliminate the complex numbers.

The Final Derivative

After simplifying the derivative, we get:

d(1/tan(2x/1+x^2))/dx = (-2(1+x2)2 + 4x(1+x^2)) / ((1+x2)2 * tan2(2x/1+x2))

Conclusion

We have used various mathematical techniques, including the chain rule and the quotient rule, to simplify and derive the function. The final derivative is a complex expression that involves the tangent and the quadratic function.
