graphics calc - degrees sign (1 Viewer)

[caramel1]

hello
i have a graphics calculator (casio cfx-9850gc plus) and i can't find the manual and have no idea how to get degrees/minutes

can someone help me? i'm trying to do trig and it's impossible

Make sure in the normal run mode (Mode-1).

To enter an angle in degrees and minutes, press [OPTN] [F6] [F5] then the degrees/minutes/seconds button comes up as [F4].

To convert an answer from a decimal value to degrees, minutes and seconds, press [OPTN] [F6] [F5] then the conversion button comes up as [F5].

The nice thing about the calculator is that all those buttons will stay at the bottom of the screen once you selected them, so you won't need to press all the F buttons everytime you need to use them. They will disappear though if you change modes, but it's easy to get them back again!

For example to work out the value of sin 3216', press:
[sin] 32 [OPTN] [F6] [F5] [F4] 16 [F4] [EXE]
and you should get 0.5338605056 as the answer.

Or to find x if tan x = 0.678, press:
[SHIFT] [tan] 0.678 [EXE]
then press:
[OPTN] [F6] [F5] [F5]
and you should get 348'14.17" (348' to the nearest minute).

Hope this helps!

you can survive without a graphic calculator but can't you?

otherwise i need to get myself one...

Yes. You can survive without a graphics calc. Especially if you're doing HSC this year, and haven't already used one!

But I'll swear by mine. Stats are a lot easier and quicker. Financial Maths is heaps quicker. And the equation solver is very useful as well.
