Typing:
ACOS2S(ACOS(X) + ASIN(X))
gives, when simplified:
ASIN2C Transform the arcsin into arccos
ASIN2C has as a trigonometric expression as an
argument.
ASIN2C transforms the expression by replacing arcsin(x)
with − arccos(x).
Typing:
ASIN2C(ACOS(X) + ASIN(X))
gives, when simplified:
ASIN2T Transform the arccos into arctan
ASIN2T has a trigonometric expression as an argument.
ASIN2T transforms the expression by replacing arcsin(x)
with
Typing:
ASIN2T(ASIN(X))
gives:
