Question

If 8 sin t − cos t = 0, find all possible values of sin t and cos t

Answer 1

do you mean find all possible values of t?

Answer 2

sin t = 1/8*cos t

tan t = 1/8

t = 7.125 and 187.125

Answer 3

let 8 = R cos a and 1 = R sin a
R sin (t - a) = 0
solve this sytem of equations

Answer 4

dumbcow is correct except if you need ALL possible values of t, it would be 7.125 and 187.125 +360n
