    I apparently have no idea how to find domains....

    Here's an image from some of the work I have been trying to do, but apparently failing rather hard. If anyone would care to help me figure out where I am going wrong on finding Domains, please chime in. It's strange, as I didn't have any issues with them in Trig, but went into Calc and I...

    Hypotheses testing - apparently crying isn't going to help

    So that is the entire day wasted. I have no idea what I am supposed to be doing here, an assignment due in next week and only in the second question (which is the above). I distance learn so can't just pop and see a teacher. I am just reading this and don't even understand half of the words...

    Thought I did this right but apparently got it wrong

    Two strips of cloth with width 1 overlap at an angle a as shown. Find the area of the overlap. I swear I am missing something on this. Rhombus Area is base x height Height is 1 Let base = x unknown angle a So all I could come up with was: x = 1/sine (a) Which gave me the Area = A A = 1 *...

    Apparently, matrices of linear transformation are my weakness

    I have another eigenvector problem, where the transformation is given by T(f(x))= xf'(x) + f(2)x + f(3) . I haven't slightest clue how to represent this transformation with a matrix, and as such am completely stumped. Thanks!

    Easy enough but apparently my math tutor doesnt understand that I DONT GET IT.

    Alright so ive been talking to my math tutor from the univ. about this single question for about a week now and i HAVE to get it done. If Tan\alpha = {- 7\over24} and Cot\beta = {3\over4} For a second quadrant angle \alpha and a third quadrant angle \beta Have to find Sin(\alpha + \beta)...

    Apparently I have the wrong upper bound limit

    Question #21 and work attached. Any help would be greatly appreciated! Thanks in advance!

    Need help in forming equations for these two apparently simple scenarios!

    No. 1 Three eights of the class got sick. Three more students got sick, leaving only half the class at school. How many students were not sick? (possible choice of answer: 8, 12, 16, 20) No. 2 3/4 of a jar of lollies are multi-coloured and the rest are black. 6 of the black lollies are...

    "Super Integral" (Apparently)

    Saw this one on the univ's notice board... I don't know how hard this will be for you people, especially Krizalid, but I'm interested to see the answer. \int\limits_1^{100} {x^x } dx
