Expert Answer
In order to find the tan inverse of a number using trignometric tables, we observe the specific value for which we need to find tan inverse in the table.
examples:
Tan -1 (0.249) = 0.244 radians or 14o
Tan -1 (1.600) = 1.012 radians or 58o
From the above examples, it is clearly evident that we need to look for the value given in brackets in the table and accordingly we have to locate the value of radians or degrees given in the table for respective value given in brackets.
Finding square root using long division method is explained below.
