Question

Name the x-values for which the sine function equals to the cosine function in the domain 0°< x < 360°

Answer 1

@amistre64 please help? :)

Answer 2

Oh sorry i dont know this :\

Answer 3

@amistre64 do you know how to do this? i'm really confused.

Answer 4

when does sin(x) = cos(x) ??

Answer 5

i'm not sure

Answer 6

better yet: let x = r cos(t), let y = r sin(t) ... if its the unit circle then r=1

cos(t) = sin(t), when x=y

what sort of line does this make?

Answer 7

a vertical line?

Answer 8

no, x=y is not a vertical line ....

Answer 9

oh...ok

Answer 10

consider what it means when x=y ... it means that we can form a 4 sided object that has equal sides ....
