sin(pi*x/ four)+ one =cos(pi*x/ eight)+sqrt(two)*cos(pi*x/ eight -pi/ four)
sinus of ( Pi multiply by x divide by 4) plus 1 equally co sinus of e of ( Pi multiply by x divide by 8) plus square root of (2) multiply by co sinus of e of ( Pi multiply by x divide by 8 minus Pi divide by 4)
sinus of ( Pi multiply by x divide by four) plus one equally co sinus of e of ( Pi multiply by x divide by eight) plus square root of (two) multiply by co sinus of e of ( Pi multiply by x divide by eight minus Pi divide by four)
sin(pi*x/4)+1=cos(pi*x/8)+√(2)*cos(pi*x/8-pi/4)
sin(pix/4)+1=cos(pix/8)+sqrt(2)cos(pix/8-pi/4)
sinpix/4+1=cospix/8+sqrt2cospix/8-pi/4
sin(pi*x divide by 4)+1=cos(pi*x divide by 8)+sqrt(2)*cos(pi*x divide by 8-pi divide by 4)
