 Hi, and welcome to the session. Let us discuss the following question. The question says, in each of the coordinate exercises, 1, 2, 6, find the coordinates of the focus, axis of the parabola, the equation of the dielectrics, and the length of the latest vector. Given equation of parabola is x squared equals to minus 16. But let's now begin with the solution. Given equation, that equals to minus 16 y. The given equation involves, if the equation has an x squared term, then the axis of symmetry is along the y axis. So, axis of symmetry, parabola, is, now here, coefficient is negative. We know that if y is negative, then parabola opens downwards. Now here, coefficient of y is negative. So, the parabola opens downwards. Now the given equation of parabola is x squared equals to minus 16 y. We can write this equation as, x squared is equal to minus 4 into 4 into y. Now clearly, this equation is of the form, x squared equals to minus 4 a y. So, comparing equals to minus 4 into 4 into y, where x squared equals to 4 minus 4 a y. We find that a is equal to 4. We know that if the equation of parabola is of the form x squared equals to minus 4 a y, then its focus is at the point 0 minus a and direct axis y equals to a. So, focus parabola 0 minus 4, equation of direct axis y equals to 4, as a is equal to 4 here. Now we will find length of latest rectum. We know that length of latest rectum is equal to 4 a, now here a is equal to 4, so length of latest rectum of the given parabola is 4 into 4 and this is equal to 16. So, the focus of the given parabola is at point 0 minus 4, of symmetry is y axis, direct x is y equals to 4 and length of latest rectum is 16. This is our required answer, so this completes the session, bye and take care.
