lzfan715 Posted March 29, 2009 Share Posted March 29, 2009 I was gone the days that my Alegbra 2 teacher taught logs and nw he just says "You are a smart girl, figure it out yourself" when I ask for help. Is there anyone here who could help me understand this stuff because I am in over my head. Link to comment Share on other sites More sharing options...
jimmie ray Posted March 30, 2009 Share Posted March 30, 2009 Teachers used to encourage coming to them for extra help. Maybe too many lawsuits or claims of inappropriate behaviour changed that. I do Engineering work, but never used even a fraction of the advanced math they used to push. Link to comment Share on other sites More sharing options...

In many cases, they memorize the rules without fully understanding them, and they sometimes even manage to squeak by a course. sosmath.com/algebra/logs/log1/log Link to comment Share on other sites More sharing options...

lzfan715 Posted March 31, 2009 Author Share Posted March 31, 2009 I don't have the worksheet with me, I turned it in without finishing it but when I get it back Iwill post some of the problems because I have to know how to do it on the test. Jimmie Ray, I went to the teach. The problem is that he doesn't even have a math degree, his degree is in art. He is a bit of a pain in the butt too. It is just too much hassle to deal with him. What Richard Vernon was to the Breakfast Club, is what my math teacher is to me. Link to comment Share on other sites More sharing options...

Hard to imagine an art teacher that wouldn't get along with you, knowing your interests and outlook. I'm sure there are people in high places who know he is out of place, and cover for him (this is life, by the way). Reach out to others, as you are doing, to learn what's required. Then, write a glowing testimony for this man, and get it out to his superiors. They'll either realize something wacky is going on, and remove him, or believe it, and inform him how refreshing it is to have a student praise him. He'll have to like you or fear you - but either way, you win? Link to comment Share on other sites More sharing options...
lzfan715 Posted April 2, 2009 Author Share Posted April 2, 2009 Well, he thinks that I am a little poser. For instance I wore a Janis tshirt to school. It's bright blue tie dye with a college of pictures and it says Janis on both the front and back. He said I bet you don't even know who that is. I told him I did too, I was a huge fan. His response was Yeah, I'm sure you are. He makes me so mad. If I wear anything that is even remotely related to the 70s or 60s he is more degrading than usual. Anyway, can I apply the logarithm rules to natural logs? Link to comment Share on other sites More sharing options...

kirchzep27 Posted April 2, 2009 Share Posted April 2, 2009 If i didnt have extra help for math classes, would have never got through it. really, for people who have trouble with math, memorizing formulas should not be a necessary thing. just another added total roadblock for someone who is not inclined for math and if you can't get the formula right from the start, then its useless.

lzfan715 Posted April 3, 2009 Author Share Posted April 3, 2009 If you give me a formula I can do it. It's when they say solve this and I don't have a formula that I flip out. Like logs, and parts of geometry for instance. Link to comment Share on other sites More sharing options...

Like logs, and parts of geometry for instance. The Common Logarithm In chemistry, base 10 is the most important base. We write log x to mean the log base ten of x. Example: log 10,000,000 = log 107 = 7 and log 0.00000001 = log 10-8 ltcconline.net/greenl/Courses/154/logexp/explogeq Link to comment Share on other sites More sharing options...
kirchzep27 Posted April 3, 2009 Share Posted April 3, 2009 what about the kids in class that asked the teacher questions, like what if you put the x squared over the y, or if you just times everything by two, or cubed or whatever.... and you'd be like whaaaaa. i would always have to take notes and teach myself with the text book, total horror show w/math.

Virginia Posted April 3, 2009 Share Posted April 3, 2009 I wish I could help but Alg II/Trig/Calc were definitely not my best subjects (nor was Chem). Thankfully I haven't needed to use that type of math IRL. I did ask my daughter, who recently finished Alg II, but she hasn't had logarithms yet, I guess that will be in her next class.

eternal light Posted April 3, 2009 Share Posted April 3, 2009 If it were not for my love of astrology and passion for doing horoscope charts, I probably would have remained freaked out about logarithms. Definition of Logarithms Proportional parts of a quadrant, expressed in numbers, whereby calculations of the planets' places at a given hour, or the Arc of Direction for a given date, can be made by simple addition and subtraction rather than by multiplication or division. They were invented in 1614 by Baron Napier of Murchiston for use in his astrological calculations. Tables of Logarithms are in common use in all schools by students of trigonometry. Tables of natural, proportional and logistic logarithms are also available, each designed for different uses. An improvement in logarithms was introduced by Henry Briggs in 1624. astrologyweekly.com/dictionary/logarithms Link to comment Share on other sites More sharing options...
lzfan715 Posted April 3, 2009 Author Share Posted April 3, 2009 Virginia, chem isn't too bad. I think you have to have to have a desire to learn it though. I love it and it makes sense to me. I just really enjoy it. We just finished quantum mechanics, and it's so interesting how you affect 10 years ago by something you do know. I know it sounds crazy, but it's true.
