Find the approximate values of (i) sin 1...

Find the approximate values of (i) `sin 1^(@)` (ii) `tan 2^(@)` (iii) `cos 1^(@)`.

Text Solution

Verified by Experts

(i) `sin 1^(@)=sin(1^(@)xxpi/180^(@))=sin pi/180~~pi/180`
(ii) `tan 2^(@)=tan(2^(@)xxpi/180^(@))=tan pi/90~~pi/90`
(iii) `cos 1^(@)=cos(1^(@)xxpi/180^(@))=cos pi/180=1`
