I hope you can read cursive and I hope this helps! (:
Cot(3x)=3^(1/2)
cot(x)= cos(x)/sin(x)
cot(3x)= cos(3x)/sin(3x)
look at a unit circle chart
find a value for cos that has sqrt(3) in it
which one will reduce so that the cos/sin will equal sqrt(3)?
pi/6 radians
now cot(3x) implies that x is one third this value
pi/18 is the answer
5 × 1. = 5
_ × _. = _
8 × 4. = 32
5/32
The coefficient in (2/3q-3/4) is 2/3 and in (-1/6q-r) is -1/6
