Just noticed I should have used the sin / cos identities for killing the power first... but I'd still get stuck anyways >_<
Well, I was a lousy ass during the lessons so I ended up quite rundown by a truck when I checked out the questions.. private lessons turned out to help a great deal, but i'm stuck with this one question that i really can't move past it (i skipped it for the time being but would like getting it solved for once :P)
Solve, for real values of x, the following equation:
Trying to open it up using the sinh x and cosh x rules got me a little bit lost in it
and
Solution to that one would be awesome
One more question my brain cells just won't go past is this one:
Solve, for real values of x, the following equation:
The powers just confuse me, trying to use the identities led me to
(...messing a bit around with it...)
And from then onwards, my brain shuts down. I can't get past that =/
