▲ 2 r/maths
Hello!
I have come across a question in my maths calculator paper that is quite confusing as it doesnt have any values for the tangent point or radius.
The question is:
A circle C has equation x² + y² = r²
The point A with coordinates (p,q) lies on C.
Show that the tangent to C at A hqs equation qy + px = r²
i dont know if this is really simple and i cant do this topic or if this is actually hard... so please help!!
