Sharp EL-5230 AnsÒV 678.5840132 AnsÒV 678.5840132 V=1ı3πRŒH, Using the solver function, Example

Chapter 1: Before You Get Started

Using the solver function

You can solve any unknown variable in an equation by assigning known values to the rest of the variables. Let us compare the differences between the solver function and the simulation calculations using the same expres- sion as in the last example.

Example

What is the height of cone 3 if it has a radius of 8	h
and the same volume as cone 2 (r = 9, h = 8) in
the last example?	r

9.Store the result of step 8 on the previous page in variable V. Press j twice and ; < xV.

10.Input the equation (including ‘=’) in the NORMAL mode.

Press ;V ; =then input the rest of the expression.

You must press ; = ( m key), not e, to enter the = sign.

V = 13 πr2h

0.

11.Press I 5 to move to the variable input display.

•Note that the values assigned to the variables in the last example for the simulation calculations are retained and displayed.

12.Press d to skip the height, and then press 8 e to enter the radius

(R).

•The cursor is now on V. The value that was stored in step 9 is displayed. (volume of cone 2)

13.Press u u to go back to the variable H.

•This time the value of H from memory is also displayed.

V=1ı3πRŒH

H=z 8.

V=1ı3πRŒH

V=z678.5840132

V=1ı3πRŒH

H=z 8.
