The equation of a curve is such that \(\frac{dy}{dx} = \frac{1}{(x-3)^2} + x\). It is given that the curve passes through the point (2, 7).
Find the equation of the curve.
Solution
To find the equation of the curve, we need to integrate the given derivative \(\frac{dy}{dx} = \frac{1}{(x-3)^2} + x\).
First, integrate \(\frac{1}{(x-3)^2}\):
\(\int \frac{1}{(x-3)^2} \, dx = -(x-3)^{-1} + C_1\)
Next, integrate \(x\):
\(\int x \, dx = \frac{1}{2}x^2 + C_2\)
Combine the results of the integration:
\(y = -(x-3)^{-1} + \frac{1}{2}x^2 + c\)
Use the point (2, 7) to find the constant \(c\):
\(7 = -\frac{1}{(2-3)} + \frac{1}{2}(2)^2 + c\)
\(7 = 1 + 2 + c\)
\(c = 4\)
Thus, the equation of the curve is:
\(y = -(x-3)^{-1} + \frac{1}{2}x^2 + 4\)
