Differentiation - Tangents and Normals at a Point

Differentiation - Tangents and Normals at a Point

The curve for which \(\frac{\mathrm{d}y}{\mathrm{d}x} = \frac{a}{(1-2x)^2} + 3\), where \(a\) is a constant, is such that the tangent to the curve at \((1, -3)\) is perpendicular to the line \(7y + x + 20 = 0\).

  1. Find the value of \(a\).
  2. Explain whether this curve has a stationary point.
  3. Find the equation of the curve.
