Scenario 4: Finding an unknown quantity from the TVM Solver
N � 5
I% � 6
PV ��24000
PMT � 0
FV � ?
P / Y � 1
C / Y �1
PMT : END

N � 5
I% � 6

PMT � 0
FV � 0
P / Y � 1
C / Y �1
PMT : END
� You can set the unknown quantity to be zero in order to
execute the program. In the above example, the future
value of a compound interest problem is going to be
found. You can set FV to be zero and then choose tvm_FV
to calculate the future value.
Scenario 5: Finding an area under a curve and above the x-axis
� Apart from using the function MATH 9, you can sketch the
curve and use the function 2nd trace 7, and then set the
lower limits and the upper limits.
Scenario 6: Finding probabilities in a Binomial distribution, in the form P( X � or � or � c )
� You need to change the probability to the form P( X � C ) ,
and then use the function 2nd vars B to choose binomcdf.
