Mutual exclusivity
P(A) + P(B) = P(A or B)
2
New cards
Independence
P(A) x P(B) = P(A and B)

sin(A+B)
sin(2A)
sinAcosB + cosAsinB
2sinAcosA
8
New cards
cos(A+B)
cos(2A)
cosAcosB - sinAsinB
cos²A - sin²A
1 - 2sin²A
2cos²A - 1
9
New cards
tan(A+B)
tan(2A)
(tanA + tanB)/(1 - tanAtanB)
(2tanA)/(1 - tan²A)
10
New cards
Identity involving tanx and secx
1 + tan²x = sec²x
11
New cards
