Is there a way I can plot 5 different functions together?I only require specific sections of the graphs, like between [0,3] for the first, (3,6] for the next, etc?

Thanks!

How do I find the equations of all tangent lines (of a function) passing through a point that is not on the graph of a function? I am completely clueless, any help would be apprechiated ! THANKS

(I'm using Maple 11)
