Re: inequations & trig. eq
In a message dated 98-01-28 09:12:45 EST, you write:
<<
Yes, but how to solve x/(x-1) undefined ?
and if the inequation is a little bit difficulter for ex
(sinx-2)/(4sin^2 x -1)>2
>>
I still don't understand. What do you mean "solve". & an which calculator?
In the 2nd equation, does "sinx-2" mean "(sin(x))-2)" or "sin(x-2)" etc
My tutees' problems are usually a failure to use enough parentheses to MAKE
the calculator do what YOU intend. This follows from a lack of expertise with
the calculator's EOS.
