Find from the tables the value of
(i) sin 56o (ii) sin 56o 24' (iii) sin 56o 28'.![]()
Find 56o on 'Natural Sines' tables in 'A' group. As there are no minutes, the value is read horizontally under the 0' column.
sin 56o = 0.8290
(ii) sin 56o 24'
Look horizontally along 56o column and vertically under 24' in 'B' group.
sin 56o 24' = 0.8329
sin 56o 24' = 0.8329
sin 56o 28' = 0.8336
![]()
To find q when sine ratio is known.
![]()
\ q = 56o28'
The readings can be obtained from the tables.
