Question about Casio fx-300ES Calculator

The results of calculations involving trigonometric functions are dependents on the angle units. So if angles are in degrees the calculator must be configured so.

To set angle unit one presses SHIFT MODE to access SETUP and select the number that corresponds to the unit desired.

Your right you should be in degree mode. However, my guess is you are somehow entering in cot wrong in your calc. Recall cot = 1/tan! In your graphing calculator enter: 35(1/tan(61) = 19.4.

Hope this helped!

The calculator is telling you that the result is 7.5 times ten to the negative 3, or 0.0075 .

If you want to see the result without the exponent, change the display mode. Press SHIFT [SETUP] 6 and then specify the number of digits you want after the decimal point.

The D simply tells you that the calculator is set to Degrees. All trig functions will use degrees. If you want to change this, press SHIFT [SETUP] and select 4 for Radians or 5 for Grads.

"Input" is a command, which inputs a value. Try this:

Input X:tan^-1(1/X)

Input X:tan^-1(1/X)

Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.

because cotangent, cosecant, and secant are all inverse trig functions, just type in 1 / |shift| trig function and the number if you are finding the angles. It might not be a dedicated button, but its an extra push, and it will give you the same result. *note that I put the shift press only because that is how you get the inverse tan to get an angle from a tan ratio.*

What is wrong? Are you not getting the right answers? If so, your calculator is set on radian, not degree.

set it up in correct rig mode, mode button (several times) until you get a window showing deg - rad - grad, choose deg (degree mode)

if the sides of a triangle are 15cm ,16cm, and 17 cm ,then the area of the triangle is what ?

Put the calculator in radian mode and it will graph trig functions just fine. If you don't know how to change it to radians, then go to mode and cursor over to select radians. I am assuming you know where the sine, cosine, tangent, etc. keys are.
