Pure Math P1 Oct 2023 [Q7] Edexcel IAL WMA 11/01|Finding the Gradient, Equation of the Normal

### Topic Breakdown:
- **Finding the Gradient at Point P **
We start by calculating the curve gradient at the given point P(4, -1) using the derivative provided, explaining each step clearly.
- **Equation of the Normal**
Next, we find the equation of the normal to the curve at P using the perpendicular gradient. The final equation is presented in the form ( ax + by + c = 0 ).
- **Finding f(x)**
In the last part, we integrate the derivative f'(x) to reconstruct the function f(x), using the given point on the curve to determine the constant of integration.
### Description:
In this video, we solve Question 7 from the Edexcel A Level Pure Math P1 October 2023 exam (WMA11/01). Watch as we find the gradient at a specific point and derive the equation of the normal, followed by working through the integration to find f(x). This step-by-step tutorial is perfect for A-Level students preparing for their exams.
