How should i find the value of inverse trigonometry values. For eg:- when i was going across through ncert exercises physics class 12, Ray opics, 9.5 Question i need to find the value of arcsin(1/1.33). How could i find such values with the use of log table or any method.

Hii
You need to learn certain fractions values which are output of standard values .Hence you will get these values in terms of values

Hii
i meant to say that for standard angles learn the values in term of ratios and decimals rather than their root format .
Questions pertaining to IIT JEE will not focus on calculation finding inverse with log tables.
