Step-by-step explanation:
Here's the answer I hope it will help you
Answer:
1. y = sin(x²+C)
2. see below
Step-by-step explanation:
1. 
separation of variables

integration both sides
you should get :
remember constant of integration!!
2. y = sin(x²+C)
3 = sin(0+C)
y(0) = 3 does not have a solution because our sin graph is not shifted vertically or multiplied by a factor whose absolute value is greater than 1, so our range is [-1,1] and 3 is not part of this range
X = t/2. t = 2x
y = 3t^3 - 1
y = 3(2x)^3 -1
y = 24x^3 -1
