About solving equations
You can use the HP 49G numeric solver to solve foiu" types of equations.
You select the type of equation that you want to solve from the numeric
solver choose list.
To access the numeric solver choose list, press
The following options are available from the choose list;
® Solve equation
Use this option to solve an equation for an imlmown variable. For
example, you can use the this option to solve the following equation
for x:
4sin(x) + 5 cos (,r) In (a:" + 3) = 0
Solve polpiomial equation
Use this option to find the roots of a polynomial equation. For
example, you can use this option to find the roots of the following
polynomial:
5x'" + 4;r” - 3,r + 2
Solve linear systems
Use this option to solve a system of linear equations, that is, a set of
simultaneous equations. For example, you can use this option to solve
the following simultaneous equations to find the value of x and y.
3x + 2y
2x 8y 7
Solve differential equation
Use this option to solve first order differential equations, that is an
equation that contains a derivative. For example, the following first-
order differential equation describes the rate of radioactive decay:
