Obviously retouched profile pics . Anyone who ' s touched Photoshop can tell you spent 20 minutes with the airbrush tool and it makes you seem vain and phony and easily insulted . <| sep |> Time to farm the Pelago , friend <| sep |> Holy fuck . I ' ve never seen the video before . That is so well done <| sep |> Sine is the Y value of a line drawn at an angle . Cosine is the X value . To get a better idea of what I mean , suppose you draw a circle of radius 1 at the origin of a graph 0 , 0 if you were to draw a line at any angle from the centre of the circle to the edge , the sine of that line would be the distance along the Y axis that the line covers . If you were to turn the line into a rightangle triangle with both of the legs parallel to each of the axes of your graph , the sine of the angle would be equal to the length of the line parallel to the Y axis . I don ' t understand the second part of what you asked why it ' s done what way ?
