J.P. McCarthySome help:

Q. 2 (a)

(i) The determinant of a matrix

is given by (right-down-diagonal minus left-down diagonal).

Thus you have to solve:

.

(ii) Put … surely you know how to add and transpose matrices?

(iii) .

Q. 3 (a)

(ii) The slope of the curve is given by so solve

.

When you find the t(imes) at which this happens, substitute into the and to find the coordinates.

(iii) Use the formula:

.

(c)

With , the partial derivatives evaluated at the measurements, and , solve

,

for .
