    Use the trapezium rule with four ordinates (three strips) to find an approximate value for?
    Integral (limits 3-0) sqrt(2^x) dx

    (How do you find the width of first and second strip, 1st height, sum of mid heights and find the last height, with no diagram)

    Also when would you sub the limits into the integral and then minus them?

    Thanks

    Why do you think you need a diagram?

    Work out the value of your function for x=0, 1, 2, 3

    Plug them into the trapezium rule

    P.S. there's a maths forum which is probably a better place to post questions in future, more maths folk there who are likely to respond more quickly
