Acknowledgement -
“We would like to express our special thanks of gratitude to
our teacher – ‘Mrs. Neeta Mehta’ mam as well as our
honorable principal – ‘Mr. UK Jha’ sir who gave us the golden
opportunity to present the wonderful Mathematics
Assignment on Chapter - TRIGONOMETRY, which also
helped us in doing a lot of research and we came to know
about so many new things, we are really thankful to all of
them.
Secondly we would also like to thank our family members and
friends who helped us a lot in finalizing this project.”
