    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

    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)

    3. Using the substitution u2= 2x 1, or otherwise, find the exact value of

    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)
