Learn how to find the derivative of sqrt(x). The derivative is d/dx[sqrt(x)].
Below is the graph of f(x) = sqrt(x) and its derivative f'(x). Notice how the original function and derivative relate to each other.

Derivative:
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.
The function sqrt(x) can be expressed as x^(1/2), which makes it a perfect candidate for applying the Power Rule. The Power Rule applies to any function of the form x^n, where n is a constant exponent. In the case of sqrt(x), n = 1/2.
💡 Why this works: To differentiate sqrt(x), we first rewrite it as x^(1/2). The Power Rule tells us that the derivative of x^n is n * x^(n-1), so applying this rule to x^(1/2) allows us to proceed with the differentiation process.
Using the Power Rule, we differentiate x^(1/2) by bringing the exponent 1/2 in front and reducing the exponent by 1. This gives us (1/2) * x^(-1/2).
💡 Why this works: By applying the Power Rule, we find the derivative of x^(1/2) to be (1/2) * x^(-1/2), which can also be written as 1 / (2 * sqrt(x)). This is the derivative of sqrt(x).
The result from applying the Power Rule is simplified into 1 / (2 * sqrt(x)), which is the final derivative. This matches the standard derivative formula for sqrt(x).
💡 Why this works: The final derivative, f'(x) = 1 / (2 * sqrt(x)), is correct. This simplification confirms that we have followed the correct steps and applied the Power Rule properly.
