a function plotter (copied from wims):
y =  instructions as below. allowed functions: abs (absolute value), sqrt (square root), exp (where exp(x) = ex), log (natural log), sin, cos, tan, cot, sec, csc, and more which you probably don't need to know.
Range: x from to   y from to
a curve plotter (copied from wims):
instructions: type the equation into the box and click 'plot'. for an exponent, use ^ (shift-6). for multiplication, just write the operands next to each other or use * (shift-8). for division, use / (forward slash). examples
Range: x from to   y from to
please tell me if the plotter stops working.

NOTE: in the subject line, include "m305g am" if you are in the morning class and "m305g pm" if you are in the afternoon class.

note: you are welcome to call me (475-8684) if you want to try to get an immediate answer, but i never check my phone messages (ever), so if i don't answer the phone, you better email me.

HANDOUTS

IMPORTANT: you are responsible for knowing EVERYTHING in the handouts, even if i forgot to mention it in class! keep your policy handout. do not lose it! read the homework guidelines and follow them. be aware of when tests and other important dates are. know the absence/make-up policy. etc.

trigonometry handouts

trigonometry is a very visual subject. therefore i have collected a variety of diagrams -- and even some animations -- from around the web to help you visualize important concepts.

ANNOUNCEMENTS

  • aug 30. welcome to precalc!

  • aug 30. i have created a discussion forum on blackboard (see link at top right of this page). perhaps you will find it useful and perhaps not, but it is there. you will have to log in with your UT EID.

  • sep 6. morning class: i assigned the wrong problems! please ignore everything from 1.2 for now. if you already did them, that's fine, but they will be due monday instead. to see what today's assignment should have been, scroll down and check the homework.

  • sep 6. afternoon class: as mentioned in class today, i changed my office hours from 2-3 to 1:30-2:30, same days.

  • sep 8. morning class: to remind you of what i said in class and be perfectly clear: whatever problems from 1.2 and 1.3 that you didn't hand in today, are due on monday. scroll down and check the homework.

  • sep 11. morning class: reminder of new office hour. wednesday office hour change from 9-10am to 11-12am. so in summary: MF 9-10, W11-12.

  • sep 22. concerning the test next wednesday: i haven't made it yet, but it will likely be all multiple choice, between 10 and 20 problems, and you should have no trouble finishing in 50 minutes -- or less -- if you are prepared. no calculators, no notes. some formulas supplied - see handout.

  • sep 23. i scanned aidali's notes - a complete set so far! if you were a late add, or you missed a day, you might find them useful. thanks aidali!

  • see the new "handouts" on trigonometry! (go down to "handouts")
