Question

1)

Let y be the solution of the equation

y ′ = 4(x^4)*sin(x^4) satisfying the condition y ( 0 ) = − 1.

Find y ( pi^1/3 ).

2)

Find the largest value of the parameter r

for which the function y = e^(rx) is a solution of the

equation y ″ − 14 y ′ + 28 y = 0.

3)

Let y ′ = − 4x^2*e^(-x^4) and let y ( 0 ) = 1.

Find ln ⁡ ( y ( 2 ) ).
