I'd like some Geogebra files on here:
media type="custom" key="21055422" align="right"
 * [[file:Calculus Derivative Sin(bx).ggb]] || [[file:Calculus Derivative x3.ggb]] || [[file:Calculus Motion in a straight.ggb]] ||
 * Shows the tangent to, and the derivative of aSin(bx) with sliders for a and b. || Shows the relationship between tangent, first and second derivative to a third degree Polynomial (cubic). || Shows how Motion in a straight line relates to (mostly) cubic polynomials ||
 * [[file:Calculus Integral of 1onX.ggb]] || [[file:Calculus Average rate of change x2.ggb]] || [[file:Calculus Lower Upper Sums Integral.ggb]] ||
 * An activity to find the Integral of 1/x using the are under the curve. || Shows how average rate of change no longer exists when B is moved on top of A || Calculate lower, upper sum and Integral. Allows input of your own function and boundaries. ||
 * [[file:Stats Line Of Best fit.ggb]] ||  ||   ||
 * For the new topic "Linear Modelling" try to find the line of best fit by minimising the residuals (squared errors). Check your answer using the build-in regression tools. ||  ||   ||

(4) Check the 'answer' checkbox. What is that function called ? Hint: look at x>0 only.
