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.

Choose all the options that are examples of volume:
Ulleksa [173]

Answer:

2. The amount of soup in a can

3. The amount of chips in a bag of chips

5. The amount of chocolate that makes up a chocolate bar.

Step-by-step explanation:

Volume is the amount that a substance or object occupies, or that is enclosed within a container, so 1 and 4 wouldn't make sense since 1 is a shadow that doesn't take up anything three dimensional, and same goes with 4.
