Maths Pure Flashcards
1
Q
Reciprocal Graph
A
y = k/x
y = k/x^2
2
Q
N Choose R (for use in Pascal’s triangle)
A
n! / r! (n - r)!
3
Q
Ambiguous Case
A
Sine Graph
4
Q
Differentiation
A
x^n
Becomes
nx^(n-1)
5
Q
Integration
A
(1/n+1 )x ^(n+1)
6
Q
Log Laws
A
log x + log y = logxy
log x - log y = log (x/y)
log x ^h = h log x
7
Q
Completing the Square
A
ax^2 + bx + c
a((x + b/2a) - (b/2a)^2) + c
8
Q
Differentiate e^(kx)
A
= ke^kx
