SINfjcJ
Returns
the
sine of the argument (argument must
be
in radians).
To obtain the sine
of X
when
X
is in degrees, use SIN(X*.
01 745329).
100 PRINT SIN(A*B-B)
SQRfjcj
Returns the square root of the argument. SQR(X) is the same as X[(l/2), only faster.
100Y
=
SQR(X[2- H[2)
TANfjcJ
Returns the tangent of the argument (argument must
be
in radians).
To obtain the
tangent of
X
when
X
is in degrees, use
TAN(X*. 01745329).
100 Z
=
TAN(2*A)
NOTE:
A
