Could anybody please help me with how to tackle fp3 locus questions.
There is a question in the FP3 edexcel book, which mentions:
"the tangent to the ellipse with equation x^2/a^2 + y^2/b^2 = 1 at the point P(acost, bsint) crosses the x-axis at A and the y-axis at B.
Find an equation for the locus of the mid-point of AB as P moves round the ellipse."
I have completed the question with the help of the book, however I cannot comprehend the second part of the question: "for the locus of the mid-point of AB as P moves round the ellipse": what does this mean?
who are introverts?
