Question about Texas Instruments TI-36 X Solar Calculator

Re: Cosec Function - Texas Instruments TI-36 X Solar Calculator Calculators

Cosec = 1/sin and sec = 1/cos

Posted on Oct 04, 2007

The Casio FX-260 does not offer this function as a single key operation. However, calculating sec(x) is simple as sec(x) = 1 / cos(x).

Key in x [COS] [1/x] and the wanted result is displayed.

It is the vertical line that passes through the vertex of the parabola y=x^2+10x

You can graph the function or use differential calculus to find position of the minimum.

The vertex is at (-5,-25) and the axis of symmetry is the** line x=-5**.

SEC, CSC & COT are the INVERSE of COS, SIN & TAN and are usually require hitting the "2nd F" or "Func" key of the calc to make:

SIN button work as COSEC,

COS button work as SEC

TAN button work as COT

Formulas are below:

sec x = __1 __

cos x

cosec x = __ 1
__

sin x

cot x = __ 1 __ = __cos x__

tan x sin x

Good luck!

You cannot enter it on the calculator but you can use the relation arcsec(z) =arccos(1/z)

On your calculator arccos is represented as cos^-1.

Here is a screen capture from a calculator that has the function. The arcos is computed along with the arcsec for angles in radians (top 2 lines) and in degrees (bottom two lines).

Parabolas

Open Y= editor and type in the two functions

The calculaus functions are accessible by pressing [2nd][TRACE] to open the CALCulate menu options. For the gradient (I think you mean the derivative) use option 6:dy/dx. But first choose the point where you want it calculated (use cursor to move along the curve) and press ENTER. The value of the deivative will be calculated at the chosen point.

The vertex of the parabolas are maxima. Thus you must use option 4:maximum

You will be prompted for a left bound. Move cursor to the left of the maximum (not too far) and press [ENTER]. A fat arrow is displayed on the graph that shows the left limit of the interval. You will be prompted for a right bound. Move cursor along the curve to the right of the the vertex. Press ENTER. A seconf fat arrow will be displayed to show the right limit of the interval.

You will be prompted for a guess of the maximum. Move cursor newar the max or enter a numerical value and press ENTER.

The location of the vertex is displayed (X and Y values)

I have no idea what you mean by the equation of symmetry

Intercept.

Hello,

The cosecant function is defined by

**cosec(x) = 1/sin(x) **

1[/] [sin] x.

Do not confuse this function with the arcsine function which is accessed by [2nd][sin to the -1]. When you use trigonometric functions make sure that the angle unit (Rad, dgree, grad) is the one you want.

Hope it helps.

This is a trigonometry problem not a calculator's.

**cos(x) +tan(x).sin(x) = ( cos(x) + (sin(x)/cos(x)).sin(x)**. After reduction to the same denominator (which is cos(x)) you obtain

{cos(x).cos(x) + sin(x).sin(x)} divided by cos(x).

The content of the bracket above is just 1.

Your fraction will have 1 as numerator and cos(x) as denomitor. That is exactly the definition of the secant function i.e. Function**sec** is the **reciprocal** (not the inverse) of the **cos** function, while the **arccos **is the inverse of **cos**.

A mild advice: Avoid writing function without specifying the argument (the variable on which a function acts).
