Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Yess and we just have to learn the values of some more because now we are 11 th people so we need to learn more
you wont ever be asked sin47 and sin35 values lol they'll be given to you if needed
zyada hi hai toh approximate sin47 to sin45 and sin35 to sin37
you only need to know 0, 18, 30, 37, 45, 53, 60, 90 and how those angles translate to other quadrants with the correct sign (135, 180 vagera)
36, 54 and 72 can also turn up but all of those are derivable from basic trigo if you know 18 ke values
Im asking this for class 12 boards
But boss we dont know na how to derive thts why
Me bio person
Dunno but my teacher was like remember this can be asked be prepared for worst
I think it is good if you keep in mind
arey tum logon ko bhi toh physics mein basic trig identities sikhayi jaati hain ðŸ˜
right?
...nhi
Atleast convert karna to nhi
This thing defs no
oh nvm then
