Now its my turn to come across evil logarithms....-pirate was wondering if some1 could help with this... 1) sketch the graph : y = logax Note: the a is log base a b) is it possible for the gradient of this graph to be the same as the y value for all the values plotted? thanks in advance.
You can't really sketch it, you have to make a table of values with a few key points and then draw the rest. So just re-arrange it to exponential form, a^y=x and sub points in.
no i do believe there is a sketch, its of a lnx graph, i think the graph i showed is the one u need to know cos i learnt that in maths last year.
