Graphs of Geometrical Curves


-This book contains graphs of:
Straight Line
• Straight line: (passes through origin)
Circle
• Central form of circle : x2+y2=a2
• (x – h)2+(y – k)2= a2
• General form of circle : x2+y2+ 2gx + 2fy + c = 0
• Equation of circle when end points of diameter (x1, y1) and (x2, y2) are given
Parabola
• y2 = 4ax
• y2 = – 4ax
• x2 = 4ay
• x2 = – 4ay
• (x–h)2 = 4a(y–k)
Ellipse
• Ellipse (horizontal and centre at origin)
• Ellipse (vertical and centre at origin)
• Ellipse(centre shifted to (h, k))

Hyperbola
• Hyperbola (centre is at origin)
• Hyperbola (conjugate hyperbola and centre is at origin)
• Hyperbola (centre is shifted to (h, k))
• Rectangular hyperbola
