6.38 * .10

x *.4

= 60

I'm going to guess he needs at least 60% to pass, which is a C, so thats why he's asking. This is only a guess, ofcourse.

75.3 * .5 + 6.38 * .10 + 54.28*.4

Hey /sci/

I've got a Cal 2 exam tomorrow and I was wondering if you guys had any tips on remembering Cos and Sin derivatives and anti-dev.

i always forget in which scenarios they become negative.

Just write it in the inside of a cough drop wrapper and then pretend you have a cold while taking the test. No teacher is going to not let you have cough drops in class.
