You can put this solution on YOUR website!
your equation is y=cot(x-pi/4)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "below is the graph of the equation of y = cot(x) and y = cot(x - pi/4).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the graph of y = cot(x) is in orange.
\n" ); document.write( "the graph of y = cot(x - pi/4) is in black.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you will see that the graph of y = cot(x - pi/4) is shifted to the right of the graph of y = cot(x) by pi/4 radians.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the normal interval of the cotangent function is 180 degrees, or pi.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this means the graph repeats every 180 degrees, or every pi radians.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "interval shown for y = cot(x) is 0 to pi.
\n" ); document.write( "interval shown for y = cot(x - pi/4) is pi/4 to 5pi/4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the general form of a sinusoidal type wave is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = a * sin(b * (x-c)) + d or:
\n" ); document.write( "y = a * cos(b * (x-c)) + d or:
\n" ); document.write( "y = a * tan(b * (x-c)) + d or:
\n" ); document.write( "y = a * cot(b * (x-c)) + d or:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a is the amplitude
\n" ); document.write( "b is the frequency
\n" ); document.write( "c is the horizontal shift
\n" ); document.write( "d is the vertical shift.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin and cos are sinusoidal type of wave with a period of 360 degrees because their pattern repeats every 360 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "tan and cot are a sinusoidal type of wave with a period of 180 degrees because their pattern repeats every 180 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you want to find the period, frequency, phase shift, vertical shift, amplitude, and the asymptotes for the equation of y = cot(x - pi/4). \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the period is 180 degrees, or pi radians.
\n" ); document.write( "the frequency is 1 because it is now shown.
\n" ); document.write( "the phase shift is the same as the horizontal shift which is pi/4.
\n" ); document.write( "the vertical shift is 0 because it is not shown..
\n" ); document.write( "the amplitude is 1 because it is not shown.
\n" ); document.write( "the asymptotes are at pi/4 and 5pi/4.\r
