The answer is Square root of 2. ( )
They way it works is :
sec theta at 45 degre is 1 over cosine of theta or
cosine of theta is square root of 2 over 2.
Therefore you have 1 over square root of 2 over 2.
After rationalization and simplification you should have .

It is 2/the square root of 2

### How to type sin theta and cosine theta in casio fx-85MS

Since this calculator cannot perform symbolic manipulations (algebra) you never need to type in sin(theta) or cos(theta). To calculate the sine of an angle (whatever the name of the angle may be) just press the sin key followed by an angle value and the function will be calculated. same thing with any other trigonometric function.
Make sure that the angle units is set to the unit required by your calculation: degree, radian, or grad.

### Cos theta 50

To calculate the Cosine of an angle, you first make sure that the angle unit on your calculator is set to the correct one (degree, or radian). After that it is all simple. Enter the angle value (50 degrees) then press the [COS] key. If you get an error then press the COS key followed by the angle value then press =.
Note if your calculator display Cos ( , with a left parenthesis, then you have to press COS first followed by the angle value and possibly the right parenthesis.
Note. The theta here is of no relevance.

### Sharp el-501w figure degree on rise run seven inch rise tweve inch run = ? degree

If you have learned about the trigonometric ratios (sine, cosine and tangent) you can use the tangent of the angle.
Let your run be to the right ( along the positive x-axis) and the rise be upwards along the positive y-axis. The tangent of the angle is
tan (theta)=rise/run=7.5/12
If the calculator is set with angle unit in degrees, the angle is obtained as the arc tangent of the (rise/run) value.

theta= arctan(7.5/12)=32.00538321 or about 32 degrees.

The arctan is the inverse of tan. To access it on the calculator press [2nd F][tan]
Depending on the calculator (sorry I do not have your model under my eyes)
Press [2nd F][tan] ( 7.5/12) [=]
or
7.5/12 = then [2nd F][tan] [ALPHA][Ans] [=]

### When calculating trignometric values i always get a wrong answer what can i do to reset or delete memory for a casio fx82ms scientific calculator plz help

It is most likely that the angle unit is not set to correspond to the angle unit you are using in your problems. If your problems call for angle unit in degrees, set the calculator to do its calculations in degrees. If your problems require the radian angle unit, set your calculator accordingly.

### A person walks 25.degree north of east for 3.10 km.How far would she have to walk due north and due east to arrive at the same location?

3.10 km times sine of 25 degrees is about 1.31 km.
3.10 km times cosine of 25 degrees is about 2.81 km.
The person would have to walk 1.31 km north and 2.81 km east.

Since you didn't specify the make and model of your calculator, I'm afraid I can't give you the keystroke sequences to calculate these results.

### My calculator wont graph when it's set to POL (polar) in MODE! do i need to change something? if so, what? its a new problem but i need my calculator tomorrow!

Before graphing deactivate the statistical plots: Press [2nd][Y=] to access the (STAT PLOTS) configuration screen and press [4:PlotsOff][ENTER]

To draw polar graph, make sure in MODE, POL is highlighted.
Make sure that the angle unit is set to RADIAN
If you want the angle unit to be in degrees you must open the WINDOW editor to modify the values of Theta max to a significant value: 30, 45, 60, 90, 120, 180, 360, otherwise the calculator will take the default value 6.28 (2*PI) in degrees

### I've read that the Casio fx-115ES does a great job working with complex numbers, but I haven't found it to be so simple. I am looking for an easy way to convert from rectangular to polar form and back. It...

You can perform coordinate conversions in the COMP, STAT, MATRIX and VECTOR Modes.
Angle unit may be in either degree or radian.

To convert from rectangular to polar, (SQRT(2)/2,SQRT(2)/2)

Press [SHIFT] [+] (Pol)
Screen displays Pol(
Type in SQRT2
Use right arrow to move cursor out of radical
Type in /2 [SHIFT] [,]
Type in SQRT2
Use right arrow to move cursor out of radical
Type in /2
Close the right parenthesis
Screen displays Pol (SQRT2 /2, SQRT2 / 2)
Press [=]. Display echoes the command on top line and result in bottom line as r=1, theta =45, (if unit is in degree) or theta = 0.7853981634 if unit is radian.

To convert from polar to rectangular coordinates
Note: You cannot use the answer memory to convert back to rectangular because the calculator will use the r-value only. So you will have to enter the radius AND the angle.

ex: Rec(1,45)
Angle must be in degree
Press [SHIFT][-] (Rec)
Screen display Rec(
Type in 1 [SHIFT] (,) 45 [)] [=]
Calculator displays X=0.7071067812, Y=0.7071067812
If you press the SD key hoping to convert the decimals to radicals, the calculator will not do it.

As to the "confusion", I have found none.
After you finish entering the argument of a square root, use the right arrow to move cursor out of under the root symbol to signify that the argument is complete. If you use a left parenthesis inside the root, you must insert the matching right parenthesis inside the root, then move cursor outside the root.

This is how the calculator behaves, and I am not expressing an opinion on how simple or complicated that is. I assume that to make full use of the calculator capabilities, one has to converse with it, using the syntax it understands.
