Best ResponseYou've already chosen the best response.1now as we know sin 30 =0.5 so sin 15 = 0.25 now arcsin (0.25) = 15 degress okay ?? @mathway

Best ResponseYou've already chosen the best response.0Why did sin 30 become sin 15? Is it because we ant to get the half of it (to get 0.5)?

Best ResponseYou've already chosen the best response.0And I didn't know sin 30 =0.5. Yikes!

Best ResponseYou've already chosen the best response.1it is in table of trigonometry , you should remember the whole table yourself sin 30 degree = 0.5 so sin 15 degree = 0.25 okay ???

Best ResponseYou've already chosen the best response.0Since arcsin1/4 is equals to 15, we now need to get the cos of 15?

Best ResponseYou've already chosen the best response.0I was looking up for the tigro table, but I don't know which one is that. Could you please tell what it looks like? :)

Best ResponseYou've already chosen the best response.1yes you are correct arcsin (1/4) = 15 we need to know what is the value for cos 15 we do same for cos 15 as we do for sin 15 I mean first we take our the value of cos 30 which is cos 30 =0.866 so what will be the value for cos 15 Tell me your self

Best ResponseYou've already chosen the best response.0Is it the half of 0.866?
