54 A level Mathematics Edexcel Paper 1 2018 Q9 Part a)

In this video, we work through question 9 from the EdXL Paper 1 from 2018 for 8 of months. We begin by showing the result of differentiating the equation of an ellipse, x squared minus 2xy plus 3y squared equals 50. This involves using implicit differentiation, the product rule, and the chain rule to find dy/dx. We meticulously differentiate each term with respect to x, carefully handling the terms involving y. Finally, we rearrange the differentiated equation to isolate dy/dx and arrive at the desired expression. Visit AxiomTutoring.com and subscribe to @AxiomTutoringCourses.
