Okay, so we know that why he could be a sign of B X off Lloyd's betweennegative a and A and has the amplitude of after the value of a and they have 1/2 sign of two X in this form our amplitude. Hey, if you go to stab street value 1/2 of 1/2 and a sign of accident A form a fine BX its amplitude a good one. So the function 1/2 sign of two exes don't have the same haven't absolute to That is twice that of China back what it even is all.
