MATHS Options

The MATHS menu is shown in the figure (below). This menu allows mathematical operations to be applied to curves. These options are self explanatory and work on the y-value of the curve (except where explicitly stated).

Note: Trigonometrical functions expect the user to work in radians.

SQRT	The square root of a curve.
LOG	Natural log (to base e)
EXP	e to power of
LOG10	Log to base 10
**n	Raise to power n
LOG(x)	Natural log (x-axis values)
LOG10(x)	Log to base 10 (x-axis values)
SIN	Sine (radians assumed)
ASIN	Arc sine
COS	Cosine
ACOS	Arc cosine
TAN	Tangent
ATAN	Arc tangent
ATAN2	Arc tangent using two curves
