Question

help with trig please! (problem attached)

Answer 1

oh ya the answer is A

Answer 2

for sinx=y, if x is in quadrant 1, the bigger the x then the bigger the value of y
if in quadreant 2, then vice versa, the bigger the x then the smaller the y
okay?

Answer 3

thanks is the answer a for both of the questions?

Answer 4

for cosx=y in quadrant 3, the bigger x is, then the bigger the y is
so guess what is the answer?

Answer 5

I don't understand the relationship that you're saying with bigger x and y @edwinls9

Answer 6

Oh okay, now

Cos t = -0.42
Cos w = -0.08

-0.08 is bigger than -0.42
right?
then w must be bigger than t
:-)

Answer 7

i thought it would be t is bigger since cos180=-1 while cos260=0 so the -.80 would be closer to 180 so it would be smaller, so w would be smaller than t?

Answer 8

oh ya i write wrong numbers, it should be -0.80 not -0.08. then you are right! Congrats! :-)

Answer 9

thanks!
