k Σ Calculations
To perform Σ calculations, fi rst display the function analysis menu, and then input the values
using the syntax below.
Σ Σ
Example To calculate the following:
Σ Σ
k = 2 k = 2
Use
A
x-da,(K)+f,
a,(K),c,g,b)w
<Math>
A4(MATH)6( )2( Σ( )a,(K)
x-da,(K)+f
a,(K)
# The value of the specifi ed variable changes
during a Σ calculation. Be sure to keep
separate written records of the specifi ed
variable values you might need later before
you perform the calculation.
# You can use only one variable in the function
for input sequence
