Topics covered in Circle for JEE Advanced Mathematics.
Topics in Circle
Definition and Basic Equation of Circle
- A circle is the locus of points equidistant from a fixed point (center)
- Standard form: (x-h)² + (y-k)² = r² where (h,k) is center and r is radius
- General form: x² + y² + 2gx + 2fy + c = 0
Circle Passing Through Three Points
- Three non-collinear points uniquely determine a circle
- Use general form x² + y² + 2gx + 2fy + c = 0
- Substitute three points to get three equations in g, f, c
Parametric Form of Circle
- For circle x² + y² = a²: x = a cos θ, y = a sin θ
- For circle (x-h)² + (y-k)² = r²: x = h + r cos θ, y = k + r sin θ
- Parameter θ is the angle from positive x-axis
Tangent to Circle
- Tangent at point (x₁,y₁) on circle S = 0 is given by T = 0
- For circle x² + y² = a²: tangent at (x₁,y₁) is xx₁ + yy₁ = a²
- Tangent with slope m to x² + y² = a²: y = mx ± a√(1+m²)
