That looks much too complicated! Whoever gave you this problem clearly expects that you have previously learned that the derivative of...

Apply: u = sin^{-1}(x) \frac{d}{dx}[sin^{-1}(x)] \ = \ \dfrac{1}{\sqrt{1-x^2}} so your integral becomes (1/u) du..... That should help

So if they make and sell T timers, their cost is 48000+ 8T. Their income is 14T. Those are both "linear functions" so their graphs are...

"y= x+ x" seems very peculiar as it would normally be written "y= 2x". I am inclined to think that second x was supposed to be a...
• a^4+ 2= (a-2+2)^4+ 2= (a-2)^4+ 4(2)(a-2)^3+ 6(4)(a-2)^2+ 4(8)(a- 2)+ 18= (a- 2)((a-2)^3i+ 8(a-2)^2 24(a- 2)+ 32)+ 18. That will be...

Hey, could'nt find a solution for this. I also attached my try. Help would be appreciated.
• San1998 reacted to JeffM's post in the thread Help with linear equation with Like.
Because part d is dependent on parts a, b, and c, we cannot possibly understand where you are having difficulty in part d without...
• Did you mean: find all numbers that satisfy the following: (a−2)|(a^4+2) If you did - then edit and fix your post. Those parentheses...
• No, you can't. You can say at a specific time that you started doing something. After you stop doing that thing, then you can talk...
• Ryan\$ replied to the thread Understanding the idea behind..
But why it's pointless to talk at specific time? That's what confusing me .. In real life analogy you can say at specific time I do...
