Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is $y = 5sin3x$

Step-by-step explanation:

From the question we are told that

$y = c_1\ cos3x + c_2 \ sin 3x$

given that y(0) = 0

We have that

$c_1\ cos3(0) + c_2 \ sin 3(0) = 0$

=> $c_1 = 0$

This means that

$y = c_2 \ sin 3x$

We also given that

$y[\frac{\pi}{6} ] = 5$

$c_2 sin (3 * \frac{\pi}{6} ) = 5$

=> $c_2 = 5$

Hence

$y = 5sin3x$
