## Main Question or Discussion Point

I dont get it guys. 100% on all the quizes and homework. 42% on the final.... Deptartment policy is that you have to get a 60% or above on the final to get a D no matter what your grade is. i understand integration by parts just fine, trig sub just fine, integration with trig functions, parametric equations and taylor series. I even understand the diff EQ and linear algerbra they put on the final for the most part. the only thing i forgot, was how to find slope of a tangent line when just given r=cosa. i know its a long formula and i forgot it. ticks me off that i have to repeat it. i have never had a test so low. I mean, even my trig final i failed was 55%. This sucks that i failed trig and now this class. the integration on the exam was not to bad either

∫1/√x^2+9 dx

∫te^-3t dt

then some bogus initial condition problem that made no sense. dont remember the whole thing but it was something like this

xy`-y=x^2 +5 y(0)=1/2 i think. or something weird like that. i think it is dumb they are adding diff eq to the finals now.

i dont get it. seriously, it should have been an easy exam.
