Question

Use the graph of y=sin2θ to find the value of sin 2θ for θ= pi/4 radians

Answer 1

Answer:

1

Step-by-step explanation:

Answer 2

The graph of sin function is a curve as shown below:

Now, Sin 2Ф , where Ф = $\frac{ \pi } {4}$

or sin 2Ф = 2 × $\frac{ \pi } {4}$ 

or sin 2Ф = $\frac{ \pi } {2}$ 

Ans, sin π/2 = sin 180/2 = sin 90 = 1

Thus, the curve has maximum at 90.
