There are 3 types of coordinates:
Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:
1.Inner divide.
Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:
Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:
Find out area of a triangle:
Equation of X-axis,y=0
Equation of Y-axis,x=0
Equation of one point movement straight line:
Equation of two point movement straight line:
Circle.
If center is main point and radius is a then equation of this circle is:By expanding it we found:
It's center is(-g,-f) and radius,
Conics.
Equation of parabola:
Equation of ellipse:
Equation of hyperbola:
At first you can print it and then hang it infront of your table.
After that you can get help form it.
