There are two roots of this function found by using function @ROOT within the plot

environment. Because of the integral in the equation, the root is approximated

and will not be shown in the plot screen. You will only get the message

Constant? Shown in the screen. However, if you press ` at this point, the

approximate root will be listed in the display. Two roots are shown in the right-

hand figure below.

Alternatively, you can use function @TRACE @(X,Y)@ to estimate the roots by tracing

the curve near its intercepts with the x-axis. Two estimates are shown below:

These estimates suggest solutions x = -1.9 and x = 3.3. You can verify these

“solutions” by evaluating function Y1(X) for X = -1.9 and X = 3.3, i.e.,

For the normal, Student’s t, Chi-square (

), and F distributions, which are

represented by functions UTPN, UTPT, UPTC, and UTPF in the calculator, the

inverse cuff can be found by solving one of the following equations:

Θ Normal, p = 1 – UTPN(

μ,σ2,x)

Θ Student’s t, p = 1 – UTPT(

ν,t)

Θ Chi-square, p = 1 – UTPC(

ν,x)

Θ F distribution: p = 1 – UTPF(

νN,νD,F)
