To ﬁnd the value of a term in a binomial distribution, go to the Stat screen and enter

Calc—Distribution and scroll to Binomial PD. Enter the values for n, p and x and tap

.Toﬁnd more values, use and enter the required values.

Alternatively, deﬁne a

function

bi(n, p, x) = nCr(n, x) ×

∧

x × (1 − p)

∧

(n − x)

This can be used for any

binomial distribution problem.

B.6 Trigonometric functions

The choice of radian or degree measure is made

by tapping the appropriate section of the Status

bar at the bottom of the screen.

Trigonometric equations are solved using the

Interactive functions in

. Initially, we shall

consider the solution of the equation sin x = 0.5.

The exact solution is given as x = 2k +

5

x = 2k +



. The parameter k is shown as

constn(1) and constn(2) on the screen. This

indicates that these are the ﬁrst and second

parameters to be used. The screen shows the

solution when the status bar is set to Standard or

to Decimal. Tap on

to scroll across for the

rest of the solution.

In cases where the domain is limited, enter the

equation with the domain sin(x) = 0.5|0 ≤ x ≤ 2,

highlight the equation part only and then tap

Interactive—Equation/inequality—solve and ensure

the variable is set to x. After tapping EXE the

B.7 Using the Calculus menu

Four of the operations of the calculus menu are considered here. These functions appear on the

keyboard

screen and variables and expressions can be entered directly. (It is also

possible to use the options in the Interactive—Calculation drop-down menu.)
