Calculus Solution: Finding y(2) with Given Conditions
This problem involves finding the value of a function $y = f(x)$ at a specific point, given information about its derivatives and function values at other points. We use integration to find the function $f(x)$.
Step-by-Step Integration and Condition Application
-
Integrate the Second Derivative:
We are given that $\frac{d^2y}{dx^2} = 0$. Integrating this once with respect to $x$ yields the first derivative:
$ \frac{dy}{dx} = \int 0 \, dx = C_1 $
where $C_1$ is the constant of integration.
-
Apply the First Derivative Condition:
The problem states that $\frac{dy}{dx} = 0$ when $x = 0$. Substituting these values into the equation from Step 1:
$ 0 = C_1 $
Thus, the first derivative is $\frac{dy}{dx} = 0$.
-
Integrate the First Derivative:
Integrating the first derivative $\frac{dy}{dx} = 0$ with respect to $x$ gives the function $y$:
$ y = \int 0 \, dx = C_2 $
where $C_2$ is another constant of integration.
-
Apply the Function Value Condition:
We are given that $y = 1$ when $x = 1$. Substituting these values into the equation from Step 3:
$ 1 = C_2 $
So, the function is $y = 1$.
-
Determine y at x = 2:
Since the function is determined to be $y = 1$ for all values of $x$, the value of $y$ at $x = 2$ is $1$.
Conclusion
Following the integration steps and applying the given conditions ($\frac{d^2y}{dx^2} = 0$, $\frac{dy}{dx} = 0$ at $x = 0$, and $y = 1$ at $x = 1$), we find that the function is $y=1$. Therefore, the value of $y$ at $x=2$ is 1.
