The best calculators for Examinations which allow using Non Programmable calculator are
Casio fx 991 es plus.
casio fx991ex etc.
Here I am explaining some important but lesser used functions of the calci. which every engineering students must know.
firstly ther are three types of inscription on calci keys.
#one that is written in bold black or white : this function or numeral can be accessed by simply pressing that button.
#second is that written in yellow color that function be accessed by pressing SHIFT key before pressing that key function.
# third is that written in red colour .this key can be accessed by pressing ALPHA key before pressing that key
1. equation solving
a) Equation in standard form
#press MODE key
#press 5 key for selecting EQN
# choose the type of equation by pressing the numeral key corresponding to it.
suppose we have to solve 4x2 +12x + 9=0
enter it as"4", "=", "12", "=", "9" pressing ''='' gives the first sol, again pressing ''=" gives second soln. for the problem.
solving above problem in non standard way...
write the above eqn i.e. "4x2 +12x + 9=0" in same format, writing vaiable ''x'' by pressing ALPHA key then '')'' key and write "='' by pressing ''ALPHA'' key then ''CALC'' key.
for sol press ''SOLVE" key( it can be accessed by pressing SHIFT the CALC key)
then press main ''='' key and get the results .
* equation of even higher degrees can be solved by this procedure
3)Use of calci. for definite integration:
2. matrix operation.
a) matrix multiplication
# press MODE key
#select matrix by pressing 6
press AC then SHIFT
press 4
press 1 for selecting DIM
press 1 for selecting MAT A
select type of matrix and input data
press AC
press SHIFT then 4 then
select DIM by pressing 1
select type of matrix
input value then press AC
press SHIFT then 4
Press 3 then press SHIFT THEN 4 then 4 for MATB
press =
b) inverse of matrix
c)determinant of matrix
3. Indefenite integration
