Got no clue .. need some clues :surprised
ok i figured out 1.. bu still no clue as to .2 !
How can you expect people to help you if you don't tell them what the problem is?
In your pdf attachment (7) says "loga xy= y loga x". That is an equation, not a "problem". What are you to do with the that equation?
(2) says "[itex] x\in [-1, 1] cos(arcsin x)= sin(arccos x)"
Again, that is an equation. What are you to do with it.
I had to prove the equation, but I figured it out.
Same for 2, I need to prove the equation and not just asume that it exists!
That one I couldnt prove..
Number 1 was just the power rule. Number 2 I don't know either sorry.
Separate names with a comma.
