## example program

this key sequence implements the triangle formula *c = sqrt(a^2+b^2-2*a*b*cos
theta)* to find the length of the side opposite sides *a* & *b*
including angle *theta*.

x<>m 1 * HLT x<>m 2 * HLT F cos * 2
+/- = x<>m 3 mr 2 * = m+ 3 mr 1 * = + mr 3 = sqrt HLT

to execute, enter *a*, press *S* to
start, enter *b*, press *S* again, enter *theta* and press *S*
again. the display halts with the length *c*. be sure to switch to degrees
if necessary. it appears that *S* continues the program, pressing *C*
to clear automatically resets the program counter to the beginning.
