- 1How to find gradientdy/dx
- 2What is the graident like in parallel lines?m1=m2
- 3What is the gradient like on perpendicular lines?m1*m2=1
- 4How do you find the equation of a parallel line?The gradient should be the same as m1 then you just plug in co-ords into y=mx+c to find the c
- 5What is the graident of the line perpendicular to y=3x+2-1/3
- 6How do you find the distance between two points?Pythagoras
- 7How to find the midpoint?It is like the average of the two points.
X1+X2/2
Y1+Y2/2 - 8How do you find where two lines intersect?either simultaneously or rearrange so they equal each other.
- 9Circle equation where the centre is 0,0 and diametre of 10 where the centre is -2,3 and radius of 7- X²+Y²=25
- (X+2)²+(Y-3)²=49 - 10When we rearrange (X-H)²+(Y-K)²=R² what do we find?co-efficients of X² and Y² are equal and there is no XY term.
- 11What are the three circle therom facts- the angle opposite the centre is a right angle
- radius meets a chord at 90 degrees
- radius meets the tangent at 90 degrees
