QUADRATICS
Quadratic Function |
Completing Square |
ax2+bx+c |
a(x + h)2 + k |
| |
k + a(x+h)2 |
LOGARITHMS
log_a (PQ) = log_a(P) + log_a(Q) |
log_a (P/Q) = log_a(P) - log_a(Q) |
log_a Pb = b log_a P |
log_a a = 1 |
log_a 1 = 0 |
SERIES & SEQUECES
Arithmetic Progression |
Geometric Progression |
T_n = a + (n - 1)d |
T_n = arn - 1 |
S_n = n/2 (a + l) |
S_n = a(rn - 1)/r - 1 for |r|>1 |
S_n = n/2 {a + (n - 1)d} |
S_n = a( 1 - rn)/1 - r for |r|<1 |
| |
S_∞= a/1 - r |
