You can put this solution on YOUR website!
y=sin (x+pi/4). Here, sin (bx+c), the phase shift is -c/b or -pi/4, which is 45 degrees.
\n" ); document.write( "The parent graph is y=sin x
\n" ); document.write( " $\"graph%28300%2C200%2C-6%2C6%2C-1%2C1%2Csin%28x%29%29\"$
\n" ); document.write( " $\"graph%28300%2C200%2C-6%2C6%2C-1%2C1%2Csin%28x%2B%28pi%2F4%29%29%29\"$
\n" ); document.write( "The second graph shows the sin starting from -45 degrees or just under 1 radian (abscissa is radian scale)
\n" ); document.write( "One way to look at it is to see what it takes to make the sine 0, and here it would be to start at -pi/4 for x, for then the sin will be of 0, and that is 0. \n" ); document.write( "
