Appendix
<#016> Calculate an +1 = an + 2n (a1 = 1) as the value of an changes from a2 to a5. (Results: a2 = 3, a3 = 7, a4 = 13, a5 = 21)
*1 | Assigns 1 to a1. | *2 | Assigns 1 to n. |
*3 | Value of a2 | *4 | Assigns value to a2. |
*5 | Assigns 2 to n. | *6 | Value of a3 |
*7 | Value of a4 | *8 | Value of a5 |

Using SOLVE |

SOLVE uses Newton’s Method of approximation to solve an equation.
You can use SOLVE in the COMP Mode (N1) only.
k Rules Governing Equations when Using
SOLVE
•You can use the following types of syntax for the solution variable. Example: Y = X + 5, Y (Solves for Y.);
XB = C + D, B (Solves for B.)
The following shows the syntax for the log function.
Y = X ⋅ log(2 | (When the variable specification “,X” is omitted, |
Y = X ⋅ log(2,Y | the equation Y = X ⋅ log102 is solved for X.) |
(When the variable specification “,Y” is included, | |
Y = X ⋅ log(2,Y) | the equation Y = X ⋅ log102 is solved for Y.) |
(When the variable specification “,X” is omitted, | |
| the equation Y = X ⋅ log2Y is solved for X.) |
•Unless you specify otherwise, an equation is solved for X. Example: Y = X + 5, X = sin(M), X + 3 = B + C,
XY + C (Treated as XY + C = 0.)
•SOLVE cannot be used to solve an equation that contains an integral, derivative, Σ( function, Pol( function, Rec( function, or
