You do the same thing but for inverse you would hit space with t
instead of just t. So for inverse tan you would hit space with t
and then t. It's the same for inverse for the other 2 as well.
Please let me know if you need me to explain farther. I just
finished the trig and triangle unit in my grade 11 math class and
I used my apex as my calculator so I can understand what you are
going through.

Subject: [Braillenote] Unavailable Symbol in the ScIentific
Calculator
Hi,
I am trying to find the Inverse Tangent, Cosine and Sine symbol
in the Scientific Calculator of my Braillenote Apex, which has
the serial number 650320002485. However, I can't seem to find
it. My aide called about an hour ago and was told that in order
to do these symbols, you hold down the negative sign and do the
tangent, cosine or sine symbol. When I tried that, it didn't
work. It only gave me negative tangent, cosine and sine. I know
that tangent, cosine and sine are found by pressing t and t, t
and c, and t and s in KeyPlus. Can you please give me a
step-by-step procedure, if there's any, on how to do the inverse
of these symbols? Thank you.
Please reply as soon as possible.
Sincerely,
Carlos
