What does y=|f(x)| do?
Reflects values below the x-axis in the x-axis
What does y=f(|x|) do?
Reflects values of x≥0 in the y-axis
Arithmetic sequence formula
a₁+(n-1)d
Geometric sequence formula
uₙ = arⁿ⁻¹
Convergent geometric series
Convergent if |r|<1 where r is the common ratio
Periodic sequences
Sequence is periodic if terms repeat in a cycle
Vectors and angles
If the vector a = xi + yj + zk makes an angle θₓ with the positive x-axis, then cos(θₓ) = x/(|a|) and
similarly for the angles θᵧ and θz.
