SOURCE: rounding function on my TI-30xIIs calculator, it won't turn off.

This function is FIX or FSE near the dot [.] or above it, so press
[2nd] the the [FIX] where it located button [.] for example then the
dot [.] him self: [2nd] [FIX] [.]

Rate me, thanks.

SOURCE: trig functions of the TI-30XA

cosecantx = 1/sinx

secantx=1/cosx

cotangent=1/tanx

Use these identities to get at the trig functions not represented on the calculator.

Also to get the angles you need to use the inverse trig functions (for example sin^(-1) (2nd SIN))

SOURCE: how do you divide the denominator into the numerator on the TI-30

Yes, you hit the yellow 2nd key and then the back arrow (it says F D above it in yellow.) It's the last key on the bottom of the left hand row.

If you want to raise a number to another, use the ^ key located just above the divide key.

For natural antilogarithm (exponentiation of e), use 2ND [e^x] (the shifted function of the LN key).

For common antilogarithm (exponentiation of 10), use 2ND [10^x] (the shifted function of the LOG key).

To enter a decimal exponent as part of a number, use 2ND [EE] (the shifted function of the comma key, located just above the 7 key.

Square root of 39: Press 3 9 [square-root] =

[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =

[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =
