New animation explaining sine and cosine as related to the unit circle with their respective graphs    For what its worth I recently made this animation explaining cosine and sine in terms of the unit circle Please read the images description on the images page just click the image before making any remarks  This is the only representation of both functions and their relation to the unit circle I could figure out that would   Show the graph of both sin and cos in the usual orientation where the horizontal axis represents  and the vertical the value of the function   The graphs shown when animated would not be drawn inverted when  increases the point in the unit circle moves counterclockwise as usual  The bent way I used to represent cosine was necessary in order to have the graph y  cos in the usual orientation condition  above otherwise it would have to be vertical and users would have to tilt their heads in order to see the graph properly This not only would be very lazy but it would be a terrible idea because   There would be a huge empty square between both graphs The animation frame would be too large and mostly empty space This space would not be useful for anything else that wouldnt be conveyed better in the accompanying article or image description   There would be no way to compare both graphs at once  Therefore his odd format is justified Notice that this bend could be done either to the left or to the right However if to the right the graphs would be drawn backwards in the animation as they would be drawn from the left and not to the right as it is currently This breaks condition  mentioned earlier  Im not sure if everyone would be OK with including this animation in the article I couldnt figure where to place it anyway So for now Im just letting you guys know this animation exists Cheers
