on page number 59 there is a formula of tan(delta) where there is a positive sign in denominator. There should be a negative sign in denominator.

this book is just awesome. i have read 3 books but got nothing from them but this book is so interesting that i am loving it this book is the reason that i am able to get waves and oscillation in my head this book is just amazing for me....
