We use the derivative of 10x, which is 10, as a measuring tool for how the linear function changes in response to a slight change in x. Derivatives help us calculate profit or loss in real-life situations. We will now talk about the derivative of 10x in detail.
We now understand the derivative of 10x. It is commonly represented as d/dx (10x) or (10x)', and its value is 10. The function 10x has a clearly defined derivative, indicating it is differentiable within its domain. The key concepts are mentioned below: - Linear Function: A function of the form f(x) = mx + b. - Constant Rule: The derivative of a constant multiplied by a function. - Power Rule: Used for differentiating polynomials.
The derivative of 10x can be denoted as d/dx (10x) or (10x)'. The formula we use to differentiate 10x is: d/dx (10x) = 10 The formula applies to all x since it is a linear function with no restrictions on its domain.
We can derive the derivative of 10x using proofs. To show this, we will use the basic rules of differentiation. There are several methods we use to prove this, such as: - By First Principle - Using the Constant Rule - Using the Power Rule We will now demonstrate that the differentiation of 10x results in 10 using the above-mentioned methods: By First Principle The derivative of 10x can be proved using the First Principle, which expresses the derivative as the limit of the difference quotient. To find the derivative of 10x using the first principle, we will consider f(x) = 10x. Its derivative can be expressed as the following limit. f'(x) = limₕ→₀ [f(x + h) - f(x)] / h Given that f(x) = 10x, we write f(x + h) = 10(x + h). Substituting these into the equation, f'(x) = limₕ→₀ [10(x + h) - 10x] / h = limₕ→₀ [10x + 10h - 10x] / h = limₕ→₀ 10h / h = limₕ→₀ 10 f'(x) = 10. Hence, proved. Using the Constant Rule To prove the differentiation of 10x using the constant rule, We use the formula: d/dx (c·f(x)) = c·d/dx (f(x)) where c is a constant and f(x) = x. Applying this rule, d/dx (10x) = 10·d/dx (x) Since d/dx (x) = 1, d/dx (10x) = 10·1 = 10. Hence, proved. Using the Power Rule We will now prove the derivative of 10x using the power rule. The step-by-step process is demonstrated below: The power rule formula is d/dx (x^n) = n·x^(n-1). Given f(x) = 10x, we can rewrite it as 10x^1. Applying the power rule, d/dx (10x) = 10·1·x^(1-1) = 10·1·x^0 = 10·1·1 = 10. Hence, proved.
When a function is differentiated several times, the derivatives obtained are referred to as higher-order derivatives. Higher-order derivatives can be straightforward for linear functions. To understand them better, think of a car where the speed changes (first derivative), and the rate at which the speed changes (second derivative) remains constant. Higher-order derivatives help us understand functions like 10x more deeply. For the first derivative of a function, we write f′(x), which indicates how the function changes or its slope at a certain point. The second derivative, f′′(x), is derived from the first derivative, but for linear functions like 10x, it is zero, indicating no change in the rate of change. Similarly, the third derivative, f′′′(x), and beyond are also zero.
Since 10x is a linear function, there are no special cases where the derivative is undefined. The derivative is always 10 for all x.
Students frequently make mistakes when differentiating 10x. These mistakes can be resolved by understanding the proper solutions. Here are a few common mistakes and ways to solve them:
Calculate the derivative of (10x·x²)
Here, we have f(x) = 10x·x². Using the product rule, f'(x) = u′v + uv′ In the given equation, u = 10x and v = x². Let’s differentiate each term, u′ = d/dx (10x) = 10 v′ = d/dx (x²) = 2x Substituting into the given equation, f'(x) = (10)·(x²) + (10x)·(2x) Let’s simplify terms to get the final answer, f'(x) = 10x² + 20x² f'(x) = 30x² Thus, the derivative of the specified function is 30x².
We find the derivative of the given function by dividing the function into two parts. The first step is finding its derivative and then combining them using the product rule to get the final result.
ABC Company calculates the production cost using the function C(x) = 10x, where x is the number of units. If x = 50 units, find the rate of change of the production cost.
We have C(x) = 10x (production cost function)...(1) Now, we will differentiate the equation (1) Take the derivative of 10x: dC/dx = 10 Given x = 50 units (substitute this into the derivative) dC/dx = 10 Hence, the rate of change of the production cost at x = 50 units is 10.
We find the rate of change of the production cost, which remains constant at 10, meaning the cost increases by 10 units for every additional unit produced.
Derive the second derivative of the function y = 10x.
The first step is to find the first derivative, dy/dx = 10...(1) Now we will differentiate equation (1) to get the second derivative: d²y/dx² = d/dx [10] d²y/dx² = 0 Therefore, the second derivative of the function y = 10x is 0.
We use the step-by-step process, where we start with the first derivative. For linear functions, the second derivative is zero, indicating no change in the rate of change.
Prove: d/dx (10x²) = 20x.
Let’s start using the power rule: Consider y = 10x² To differentiate, we use the power rule: dy/dx = 10·d/dx [x²] Since the derivative of x² is 2x, dy/dx = 10·2x dy/dx = 20x Hence proved.
In this step-by-step process, we used the power rule to differentiate the equation. Then, we replaced x² with its derivative to derive the equation.
Solve: d/dx (10x/x)
To differentiate the function, we simplify first: 10x/x = 10. Therefore, the derivative of a constant is zero, d/dx (10x/x) = d/dx (10) = 0 Therefore, d/dx (10x/x) = 0.
In this process, we simplify the given function to a constant before differentiating. The derivative of a constant is zero, which simplifies the process.
