Does anyone know any websites that have the graphs of "Sin/Cosec Cos/Sec Tan/Cot".?

Sorry, just to expand. To have the pairs on the same graph.

You can draw them yourself .... hopefully if you have got to this level of trigonometry you know what sin/cos/tan look like...! Drawing cosec,sec and cot is not difficult with this knowledge - for example - you know cosec = 1/sin. Because you cannot divide by zero, all points where sinx = 0, cosecx is asymptotic (i.e. infinity). You also know that 1/1 = 1 so everywhere where sinx = 1, cosecx = 1. Follow this until you get enough points to "join up" - the graph of cosecx should look like a set of "u"'s for postive y and "n"'s for negative y with asymptote lines to +infinity or -infinity if you draw them. You'llsee what I mean - you should be able to take it from here for the other graphs...

No, i know how to draw them easily. The problem is that im not very neat, so would prefer to do it on the net somewhere.
