I need help with just three of these please. Been struggling for at least 30mins now not knowing how to solve it and what the answers are. Please help. Thankyou!

Answer 1

Given: The function below

$y=5sin(2x)$

To Determine: The period of the given function

Solution

The distance between the repetition of any function is called the period of the function

The graph of the function is as shown below

$Period=\frac{5\pi}{4}-\frac{\pi}{4}=\frac{5\pi-\pi}{4}=\frac{4\pi}{4}=\pi$

Hence, the period of the function is π
