  • Definite integrals

    by Anna Strzelecka and 3 others

    Two quadratic graphs are sketched with some area beneath them shaded. Question is to determine the area of shaded regions using integration. The first graph's area is all above the $x$-axis. The second graph has some area above and some below the $x$-axis.

  • Anna's copy of Maria's copy of Mario's copy of Interactive Newton-Raphson method

    by Anna Strzelecka and 3 others

    Write down the Newton-Raphson formula for finding a numerical solution to the equation $e^{mx}+bx-a=0$. If $x_0=1$ find $x_1$.

    Included in the Advice of this question are:

    6 iterations of the method.

    Graph of the NR process using jsxgraph. Also user interaction allowing change of starting value and its effect on the process.

  • Min_max_v1

    by Anna Strzelecka and 3 others

    Calculate the local extrema of a function ${f(x) = e^{x/C1}(C2sin(x)-C3cos(x))}$

    The graph of f(x) has to be identified.

    The first derivative of f(x) has to be calculated. 

    The min max points have to be identified using the graph and/or calculated using the first derivative method.  Requires solving trigonometric equation

  • Mark equations

    by Picture of Christian Lawson-Perfect Christian Lawson-Perfect and 2 others

    All the answers in this question are equations. In order to mark each equation, Numbas needs to pick some values that satisfy the equation and some that don't, and check that the student's answer agrees with the expected answer.

    Any equation with the same solution set as the expected answer will be marked correct.
