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