This derivative represents the rate of change of the original function. The calculation follows standard differentiation rules as shown in the step-by-step solution below.
Recognizing that tan^2 x is a power of the tangent function, we apply the Power Rule for differentiation.
💡 Why this works: The Power Rule applies to any function in the form of u^n, where u is a differentiable function. In this case, u = tan(x) and n = 2, making it a perfect candidate for the Power Rule.
To differentiate tan^2 x, apply the Power Rule: differentiate the outer function first and then multiply by the derivative of the inner function.
💡 Why this works: According to the Power Rule, the derivative of u^n is n*u^(n-1). In this case, n = 2, so we get 2*tan(x)^(2-1), or 2*tan(x). We then multiply this by the derivative of tan(x), which is sec^2(x), leading to the final result: 2*tan(x)*sec^2(x).
Simplify the result and ensure the derivative is in its correct form.
💡 Why this works: After applying the Power Rule and the derivative of tan(x), the final derivative is 2*tan(x)*sec^2(x). This form represents the correct rate of change for tan^2 x with respect to x.
