The vertices of a hyperbola are V1(−6,0) and V2(6,0), and its asymptotes are the straight lines y=32x and y=−32x.
(i) Find the values of a and b for the hyperbola.
(ii) Write its standard equation in simplest form.
(iii) Calculate the coordinates of its foci.
(iv) Sketch the hyperbola on suitable axes, showing and labelling the centre, vertices, foci, and asymptotes.
