14.Press @ h to find the height of cone 3.

•Note that the calculator finds the value of the variable that the cursor is on when you press @ h.

•Now you have the height of cone 3 that has the same volume as cone

2.

H= 10.125

R¬ 678.5840132 L¬ 678.5840132

Right and left sides of the expression after substituting the known variables

Height of cone 3

•R→ and L→ are the values computed

by Newton's method, which is used to determine the accuracy of the solution.

Other features

Your calculator has a range of features that can be used to perform many calculations other than those we went through in the quick tour. Some of the important features are described below.

Statistical calculations:

You can perform one- and two- variable weighted statistical calculations, regression calculations, and normal probability calculations. Statistical results include mean, sample standard deviation, population standard deviation, sum of data, and sum of squares of data. (See Chapter 4.)

Equation solvers:

You can perform solvers of simultaneous linear equation with two/three unknowns or quadratic/cubic equation. (See Chapter 5.)

Complex number calculations:

You can perform addition, subtraction, multiplication, and division calculations. (See Chapter 6.)

Programming:

You can program your calculator to automate certain calculations. Each program can be used in either the NORMAL or NBASE program modes. (See Chapter 7.)
