Question

I don't understand what the answer for
sin50(degrees) > sin40(degrees) it's a true or false answer

Answer 1

Do you understand that the sine value is the y-coordinate of the angle's point of intersection with the unit circle?

Answer 2

Yes

Answer 3

OK, so think about those 2 angles.... 40* vs 50*.... and where they lie, relative to one another, on the unit circle.

Which point of intersection will have a larger y-coordinate?

Answer 4

well 50 would have a larger y value

Answer 5

Exactly. :)

Answer 6

As you move "up" through quadrant 1 on the unit circle, y coordinates will get larger, and x coordinates (cosines) will get smaller.

Answer 7

ohhh I get it thank you!:)
