HP 35s Using Calculator Memories to Help Solve Problems

In algebraic mode, type the expression like this:

Then store it in register V by typing:

Now the main formula can be calculated. First calculate the top line at the left-hand of the formula. The

value of the expression is still available, so there is no need to recall it, but to see how it all works, recall V,

calculate its arc sine and multiply by 5:

Next, divide by the arc cosine of the expression, recalling it again from V:

Now multiply by the square root of three times the expression.

Finish the calculation by pressing

Answer:

To four decimal places the complete formula evaluates to 9.8159. Calculation was considerably easier, and

the expression displayed on the upper line is simpler, because the temporary value was stored in a

memory register.
