Answer 1

hi sfb

Answer 2

sorry i lost my temper earlier

Answer 3

It's fine, @perl. Sorry for being a fluttering idiot.

Answer 4

i was wrong to say that

Answer 5

thanks for your understanding :D

Answer 6

\[\tan \theta =\frac{ opposite }{ adjacent } \]\[\cot \theta = \frac{ 1 }{ \tan \theta }\]\[\sec \theta = \frac{ 1 }{ \cos \theta }\]

Answer 7

this question is asking about exact value trig ratios

you need the triangles shown below



so find the ratios by looking at the diagrams

for cot(pi/3) find tan(pi/3) then take the reciprocal of the fraction (flip it)

and for sec (pi/4) find cos(pi/4) and flip the fraction for sec
