Re: Can anyone help me solve this porblem?Posted by Edward on September 15, 1998 at 22:12:50: In Reply to: Can anyone help me solve this porblem? posted by Ivan Li on September 13, 1998 at 22:32:51: Hello Ivan, The solution is as follows: and AH = P(cos(135*) + i sin(135*)) Since cos(45*)+ isin(45*) = q/p. Note: The "<" sign means angle. The "^" sign means "power of", "cos^2" is same as "cosine square". The "*" sign means "degree". Hopefully this can help you a little bit. Best regards, Edward : I have a problem that I cannot solve.Can anyone : ABCDEFGH is a regular octagon. The vector AB=p,
