Question

Consider g(x)=3sin2x
a) period of g
b) Sketch the curve of g, for 0≤x≤2π
-WITHOUT using a graphing calculator

Answer 1

The period is 120° (360° : 3)

Answer 2

I mean 180°

Answer 3

hm.. it's not π?

Answer 4

oh okay thanks

Answer 5

how did you figured that out?

Answer 6

A sin kx
3 sin 2x
Period = 360° : 3
so the period is 360°:2

Answer 7

so you take the 360/k ?

Answer 8

and then change it to radians? do you know how to just get directly to radians?
