Barry Boone's mock exam Que 33 says
Trignomentric operation includes- sin, cos, tan, asin, acos, atan but
same question in Mindq test gives a contradicting answer by say ing
Trignomentric operation does not include asin, acos, atan.
Can anyone please resolve the above contradiction by giving the right answer with explanation.

Functions asin, acos, and atan all are included in the Math class. Please look at the API specifications. Here is the link.

Hi Raji
yes,mindQ is having 4 Qs with wrong answers,so please check itup.
the three methods sin,cos,tan accepts a double parameter & returns the result of their transedental function,where as asin,acos,atan takes a parameter the result of a transedental function & are the inverse of above methods.
in short all these methods belongs to Math class.
