Question

1. use the graph of y = sin θ to find the value of sin θ for each value of θ. 270°

Answer 1

You can determine sinθ by looking at the y-axis and θ by looking at the x-axis.

θ = 90°, sinθ = 1
θ = 180°, sinθ = 0
θ = 270°, sinθ = -1
θ = 360°, sinθ = 0

Answer 2

Answer:

Step-by-step explanation:

We can clearly see the values of sin x at the vertical axis that is y-axis because the function is

y= sin x

$\theta$ will be at x place and the entire will be y

Hence, look at y-axis to get the value of sin x

$sin0^{\circ}=0$

$sin90^{\circ}=1$

$sin180^{\circ}=0$

$sin270^{\circ}=-1$

$sin360^{\circ}=0$

Since, The range of sinx is [-1,1] value will fluctuate between this interval only.
