i'll admit it. i'm having a problem even thinking about this issue at the moment. and as i recall in the exam i seem to have bumbled it under the time pressure. or at least i think i may have.
in the past i've always used a simple numerator and denominator and some other voodoo to calculate rise or run for slopes or stairs or whatever. i don't ever recall having to use a trig calculator in standard architectural work. i'm so used to doing this i do it without thinking and never figured out how to use the trig calculation portion on the practice exam.
i tried it once and i couldn't figure out if i had to hit the TRIG operation first and then the number or what i was supposed to do.
anyone mind refreshing my addled mind on how i would calculate the rise of something that was 50 feet across and a 2.5% slope or something - without using the trig calculator? or say calculate the percent slope from being given 80 feet across and a 1.5' (18") rise?
anyone willing and able to put in the time to post up what would be required if using the calculator in the software?
and as indicated above can anyone confirm whether or not i would /need/ to use the trig portion of the calculator in the exam?
