The trapezium rule is to be used to find an estimate for the integral

The table below shows values for x and f(x), rounded to three significant figures where appropriate.

Using the values in the table find 

(i)      an estimate for the integral using 2 strips,
(ii)     an estimate for the integral using 4 strips,
(iii)    an estimate for the integral using 8 strips.

Justify which of the estimates from part (a) will be the most accurate estimate for the integral.

The function   has  as a factor, and when  is divided by the remainder is 7. 

Show that and  must satisfy the simultaneous equations:  

Hence find and 

A curve has the equation .

Find expressions for and  .

Determine the coordinates of the local minimum of the curve.

A circle  has centre (-2, 3) and passes through the point (6, -3).

Find an equation for the tangent to the circle at P.

A training track for cyclists is in the shape of a circle made up of several lane

One lap of the inner lane is m, with each lane working outwards having a lap distance of m more than the lane immediately inside it.

During a training session, a cyclist is expected to complete one lap of each lane, starting with the inner lane, before moving onto the next one.

A cyclist trains until they have completed the first five lanes.
Find the total distance travelled by the cyclist.

There are 8 lanes in total on the training track.

Find the lap distance of the outside lane.

During a particular training session, a cyclist completes a lap of each lane but in addition, also completes a further 10 laps of the outside lane.
Find the total distance the cyclist travels during this training session.
