Differenciation
dx/dy = nax^(n-1)
Number of Differentiation
f(x) = Original Equation
f1(x) or dx/dy = Differentiate Once
fn(x) or d^2y/dx^2 = Differentiate Twice
Finding Volume, Area, Length using differenciation
Volume to Area = Differentiate once
Area to Length = Differentiate twice
Finding the tangent to a curve using differentiation
1) Differentiate
2) Substitute x coordinate in and you’ll get gradient
3) Sub coordinates and gradient into y - y1 = m(x-x1)
Finding the normal to a curve using differentiation
1) Differentiate
2) Substitute x coordinate in and you’ll get gradient
3) Find perpendicular gradient
3) Sub coordinates and gradient into y - y1 = m(x-x1)
Arithmetic Sequence
Sequence goes up by a constant term each time
Sum of Arithmetic Sequence
n/2(2a + (n-1)d)
Geometric Sequence
Sequence with a common ratio. You multiply from one term to the next. etc. a, ar, ar^2
Sum of Geometric Sequence
a(1-r^n) / 1 - r
Sum to infinity of a geometric sequence
a / 1 - r
Sequence vs Series
Sequence: order of increasing numbers
Series: Sum of terms
Converging Series
Series that add up to a number
Diverging Series
Series that reaches infinity
Discriminant
b^2 - 4ac
Discriminant with no solution
b^2 - 4ac < 0 (no real roots)
Discriminant with 1 solution
b^2 - 4ac = 0 (equal roots)
Discriminant with 2 solutions
b^2 - 4ac > 0
