1. A curve Cis described by the equation 3x2
+ 4y2
2x+ 6xy 5 = 0.
Find an equation of the tangent to Cat the point (1, 2), giving your answer in the form
ax + by+ c= 0, where a, band care integers. (7)
2. (a) Given thaty= secx, complete the table with the values ofycorresponding tox=16

(b) Use the trapezium rule, with all the values for y in the completed table, to obtain an estimate for
4
0
dsec
xx . Show all the steps of your working and give your answer to 4 decimal places. (3)
The exact value of
4
0
dsec
xx is ln (1 + 2).
(c) Calculate the % error in using the estimate you obtained in part (b). (2)

4. Figure 1
Figure 1 shows the finite regionR, which is bounded by the curvey=xex, the linex= 1, the linex= 3 and thex-axis.
The regionRis rotated through 360 degrees about thex-axis. Use integration by parts to find an exact value for
the volumeof the solid generated. (8)
