I have a problem when comes to question 2, I don't know how to put this into parametric form. And I am not sure if this is a parabola. Thanks in advance.

          If $y=4x^2$ then the $y$-coordinate of 4 times the square of the $x$-coordinate.



          Let the $x$-coordinate be $t$, then the $y$-coordinate of $4t^2$.



          Your path is given by $gamma(t) = (t,4t^2)$, where $0 le t le 1$.



          The curve $y=4x^2$ is indeed a parabola, with focus $(x,y)=(0,frac{1}{16})$ and directrix $y=-frac{1}{16}$.

Like this: login screen Nothing to be log when I run flutter run --verbose, so I logged manually. Every tapping on field, the widget called dispose -> init -> build.

But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
