Question 1062627
{{{ d }}} shifts the whole sine wave up or down
{{{ a }}} enlarges or shrinks the sine wave
{{{ c }}} shifts the sine wave to the right
{{{ b }}} determines the period
-------------------------------
Here's 3 cases ( without the other variables )
with {{{ b = 1/(2*pi) }}}. {{{ b = 2/(2*pi) }}}
and {{{ b = 3/(2*pi) }}}
-----------------------------------------
{{{ graph( 400, 400, -8*pi, 8*pi, -1.5, 1.5, sin(1/(2*pi)*x ) ) }}}
{{{ graph( 400, 400, -8*pi, 8*pi, -1.5, 1.5, sin(2/(2*pi)*x ) ) }}}
{{{ graph( 400, 400, -8*pi, 8*pi, -1.5, 1.5, sin(3/(2*pi)*x ) ) }}}
-----------------------------------------
Here's {{{ c = pi/4 }}} and {{{ b = 1/(2*pi) }}}
{{{ graph( 400, 400, -6*pi, 6*pi, -1.5, 1.5, sin(1/(2*pi)*x - pi/4 ) ) }}}
Hope this helps
