Answer 2

its r

Answer 3

i love helping

Answer 4

@mathmale

Answer 5

-1?

Answer 6

If you'd find 270 deg. on the horiz. scale and then take the corresponding value of sin x off the graph, yes, you'd get sin 270 = -1.

Answer 7

so -1 is correct?

Answer 8

Yes, it is

Answer 9

thank you
The amplitude of y = 3 sin(2x) is 3.

True

False would this be true @mathmale
