Steps for using the calculator to solving applications with
right triangles
1.
Turn the calculator on and set it to degree mode by pressing 2ndF SET UP ,
touching
B DRG
, and double touching
1 Deg
. Press 2ndF QUIT to exit the
set up menu.
2.
Given a right triangle with A = 3 and C = 6, find B and
θ
using the SOLVER.
To access the SOLVER, press 2ndF SOLVER , and press CL to delete any
equation that may appear on the screen.
3.
Type in the equation sin
θ
= with the keystrokes sin ALPHA
θ
ALPHA = a/b ALPHA A ALPHA C .
4.
Press 2ndF SOLVER , touch
A METHOD
, and double touch
1 Equation
to
choose the Equation solver. Press ENTER and see the list of variables.
5.
Press
▼
to move the blinking cursor over the A and press 3 ENTER .
Type in the value of C by pressing 6 ENTER . Solve for
θ
by pressing

2nd EXE .
6.
To use the SOLVER to find B, edit the current equation to the new equation
cos
θ
= . Do this by pressing CL CL to display the current equation sin
θ
= . With the cursor over the s in sin, press cos to insert cos. Press
DEL to delete sin. Press to move the cursor over the A in the
numerator of the fraction. Press ALPHA B to insert B. Press DEL to
delete A.
7.
Press ENTER to see the variable list. The value for
θ
and C will remain as
before. Press
▼
to position the cursor over the B and press 2ndF EXE
to find B.
