I would like to know how to solve the following kind of questions:
Calculate (without expressions of cyclometric functions):
arccos(11/14)+arcsin(-1/7)
And:
Calculate (without expressions of cyclometric functions):
2*arctan(1/2)+arccos(-3/5)
If you could generalize the method of solving these kinds of questions - please do. What kind of relations between the inverse trigonometric functions do I need to know?
Thank you by forehand,
Dobedobedo
