Adam Flashcards
Area of a rectangle
Base x Height
Area of a parallelogram
Base x Height
Area of a triangle
Base x height divided by 2
Area of a trapezium
Top add bottom divided by 2, times height.
It doesn’t matter, Rachel, I get given this one.
The volume of a cuboid
Base x height x depth
Volume of a prism
Area of cross section x length
It doesn’t matter, Rachel, I get given this one.
Volume of a cylinder
pi x (radius squared) x length
Circumference of a circle
pi x diameter
pythagoras
longest side squared equals the other two sides squared and added together
Sin (theta) =
a/c
It doesn’t matter, Rachel, I get given this one.
Cos(theta) =
b/c
It doesn’t matter, Rachel, I get given this one.
Tan (theta) =
a/b
It doesn’t matter, Rachel, I get given this one.
Speed
distance over time
Density
Mass over volume
Pressure
Force over area
Volume of a pyramid
One third of the base times the height
Quadratic Equation
minus b, plus or minus the square root of b squared minus 4 times a times c all over 2 times a.
It doesn’t matter, Rachel, I get given this one.
Sine rule (to find a length)
a over sine a = b over sine b
It doesn’t matter, Rachel, I get given this one.
Sine rule for area of a triangle
half times a times b times sine C
Cosine rule to find a side
a squared equals b squared plus c squared minus 2 times b x c x cos A
Equation of a straight line
y = mx + c
How to find the gradient
change in y over change in x
tangent and a radius…
meet at a right angle
angle at the circumference equals…
…half the angle in the centre
