Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Below is the solution:

xdy/dx = 4y
xdy = 4ydx 
∫ dy/y =∫ 4dx/x 
ln(y) = 4ln(x) + C 
y = e^[4ln(x)] e^C 
y = e^[ln(x)^4] e^C 
y = Cx^4 answer

Answer:

$sin \theta =\cfrac{7}{8}$

Step-by-step explanation:

Using the given identity, find the required value as per following steps:

$(sin x)^2 + (cos x)^2 = 1$

$(sin x)^2 = 1 - (cos x)^2$

$sinx=\sqrt{ 1 - (cos x)^2}$

$sin \theta = \sqrt{1-(\cfrac{\sqrt{15}}{8})^2 } = \sqrt{1-\cfrac{15}{64} } =\sqrt{\cfrac{49}{64} }=\cfrac{7}{8}$
