how do you find the worst case for keeping a zenor diode in breakdown. Which is the worst case below.
case 1: 11.2volts input, current 0A
case 2: 11.2volts input, current 100mA
case 3: 14 volts input, current 0A
case 4: 14 volts input, current 100 mA.

Also to calculate the max current throught the diode without exceeding its max power dissipation, Would i use the zenor voltage x the maximum regulator current. On the data sheet they list a test current and a maximum regulator current, which one do i use or what is the difference?

for constant = y=3
for identity = y=x
for quadratic = y=x^2
for cubic = y=x^3
for absolute value = y=|x|
for square root = y=√x
for reciprocal (odd power) = y=1/x
for reciprocal (even power) = y=1/x^2
for exponential (x>1) = y=10^x
for exponential (x<1) = y=10^x
for logarithmic (common) = y=log x
for logarithmic (natural) = y=ln x
and no, this isn't my homework. I know that Xs and Ys are supposed to switch...but then I don't know how to work from there. Do all these parent functions even have inverses (all)? Help please, I'm trying to understand something here. Work is appreciated!

I found out my score for my first test of the semester today and it was only a C. BARELY a C mind you I got a 71%. I studied my brains out. I read the material inside out. I memorized everything the teacher told me to. I came in for extra help everytime I had the chance. But here were like 7 people who got A's and B's and these people are studying to be chemical engineers or whatever. Are these people just smarter than me or wht is going on. Should i just drop out?

Apparently, we only use one side of the brain. So, if we can't use one side of the brain, how can some people write with thier left hand?
Why do we have one side of the brain not in use?

Suppose you want to know the last card for a deck of 47 cards or one with 102 cards and you don't have that many cards.

What would be the equation I would use to solve this problem? I know the pattern looks like this...
The 1st column is the number of cards in the deck. The 2nd is the last numbered card.

1 = 1
2 = 2
3 = 2
4 = 4
5 = 2
6 = 4
7 = 6
8= 8
9 = 2
10 = 4
11 = 6
12 = 8
13 = 10
14 = 12
15 = 14
16 = 16
17 = 2
18 = 4
19 = 6




Please let me know how you solved it and please let me know what equation will work!

I have some data (lengths and times) that I need to put into a graph using log log paper with 2 cycles. But I have no idea how to do it. The log log paper is labled 1-10 2-10 on both the x and y axis, and my data is like: (85cm, 18.7 sec), (76cm, 17.4sec)... and so on. Can someone explain it to me?
