Calculator Lab

Can you use each of these functions using your calculator?

1) clear entry vs all clear
2) change sign
3) ()
4) scientific notation
5) inverse (inv on some, 2^nd function on others)
6) square roots and squares
7) Y to X power
8) memory (store, recall, clear memory)
9) Pi
10) sin, cos, tan

 Sample problems (answers given to proper # of sig figs)

1)         (6.29 E 5) (4.39 E - 7)  =  2.76 E - 1      (0.276)

 2)         (7.80 E - 4) / (9.55 E 12)  =  8.17 E - 17

 3)         (3.243 E 5)                             =   70.74
             (1.812 E 4) (2.530 E - 1)

 4)         3 + (4 x 3) x 2 = 27

 5)         3 + (4 x 3) x 2³ = 99

 6)         3 + (4 x 3) x 2^3.1 = 106

 7)         (6.07 E - 2)²  =  3.68 E - 3        (0.003 68)

 8)         (5.45 E 2)³ = 1.62 E 8

 9)         (6.38 E - 4)⁷ =  4.30 E - 23

 10)       (6.291 E 3)^1/3 =  18.46

11)       (2.173 E 4)^1/9  =  3.033

12)       [1/3 x 6/15 + 4/13]³  =  0.086

 13)       [4 x 3²  +  (6 / 5)]^1/3       =    6.94 E - 2       (0.0694)
              (12 x 4) + (2 / 6)²

 14)       sin 9.614º  =  0.1670

 15)       tan 15.71º  =  0.2813

 16)       sin^-1 0.1745  =  10.05º

 17)       inv sin 0.9898  =  78.75º

 18)         8.33 (4 - 5.2) / ((8.33 - 7.46) x 0.32)    =  4.57
               4.3 (3.15 - 2.75) - (1.71 x 2.01)
