Find the centre of C.
(i) Show that the radius is cm. (ii) Find the total external surface area of the housing.
The housing rotates about the fixed point V so that P moves to P′ = (1, −9, 13). Find in degrees.
The housing rotates about the fixed point V so that P moves to P′ = (1, −9, 13). Find an equation of the plane through P, V and P′, with integer coefficients.
Use partial fractions to show f(x) = 3/(x + 4) − 5/(x + 2).
Show that the area bounded by y=f(x), the x-axis and x=0, x=1 is ln(486/125).
Show that the binomial expansion through x² is −7/4 + (17/16)x − (37/64)x2.
(i) Use 11c to approximate . (ii) Hence state the area between the polynomial y = −7/4 + (17/16)x − (37/64)x2, the x-axis and x=0, x=1.
The comparison area from 11d is bounded by y = −7/4 + (17/16)x − (37/64)x2, the x-axis and the lines x = 0, x = 1. Given ln(486/125) ≈ 1.36 to three significant figures, decide whether the area from 11d overestimates or underestimates the exact area.…
Find (i) ; (ii) hence or otherwise the area of ABC.
