You cannot. To evaluate an expression (not an equation or an equality) key it in and press ENTER.

SOURCE: how do i enter the formula into my calc for a

Hello,
This is for the TI-30 XIIS. It should work for you once you find the (nCr) key or the menu item under PRB key. If you know the formula skip to Exemple

Let us start with a review of the formula for the binomial distribution
f(r;n,p)=n!/(r!(n-r)!)x(p^r)x(1-p)^(n-r)

But n!/(r!(n-r)!)=(nCr) you get
f(r;n,p)= (nCr)x(p^r)x(1-p)^(n-r)

Exemple : n=25, r=6, p=0.7

f(6;25,0.7)= 25 [PRB] [-->] 6 [ x ] {0.7[ ^] 6 }[ x ]{0.3[ ^ ]19}

The arrow means a horizontal scroll once to select the (nCr) function. [ x ] stands for the multiplication sign.
[ ^] is the raise to the power key
The { } are used here as parentheses to make formula legible.

Hope it helps

SOURCE: Find theta on TI-30XS MultiView calculator... I can't :(

No, your calculator does not know a variable called theta. But what is theta but a symbol to represent a variable. Usually it is used to represent an angle in polar coordinates. It is just the usage and it is not really essential. You can do conversion from polar to rectangular coordinates and from rectangular to polar coordinates but it does not matter what the angle variable is called.
Go ahead, do all the calculations you want that involve an angle. If the calculator can perform them , they will be evaluated correctly and the name you give the angle value (alpha, beta, theta, iota...) is immaterial.

How to put in an "equal sign " into the TI-30XS Multiview calculator?


Yes you can enter basic or complicated expressions, you just can't enter equalities nor equations. The calculator cannot solve equations. When an expression (without an = sign) is entered, pressing the ENTER key will evaluate it.
