    integration questions

    please help solve:) integrate: by substitution: 1) dx/(x sqrt(x^2-4)) [x=1/u] 2) dx/[(a^2-x^2)^(3/2)] [x=asintheta] 3)(e^2x)dx/(e^4x -1) [u=e^2x] 4) cosx dx /(1+sinx)(2+sinx) by parts: 1)cos^4(x) 2)x(inverse tanx) 3) log(a^2+x^2) and....write as partial fraction: 1/(x^4 +1)...

    what to do?

    This year, my english teacher left the school and so now we have another teacher. The problem is, she doesn't seem to know much about the english course. We've done frankenstien and speeches with her. For frankenstein, she just got us to read parts of the book every lesson, then watch...

    Please help solve. The sheet they come from didn't have answers =( Integrate: 1. (2x+3)/sqrt(x^2+2X+3) 2. (5t^2+3)/t(t^2+1) 3. sqwiggle thing root 3 and -1 (definite integral): X^2/sqrt(4-x^2) 4. (3x^2 -8x^3-19x-14)/(x-3)(x^2+2) thanks people

    simultaneous with complex

    Solve for z and w: 1) (2+i)z+(2-i)w=1 and (2-i)z+(2+i)w=2 [ans: z=(3/8)+(i/4) w=(3/8)-(i/4) ] 2) z+(1-i)w=2i and w+(1-i)z=1 [ans: z=1+i w=-1] thanks

    some questions...

    alright... i'll use my brain...and giving it a go... 1. I-beams are I shaped because something about having more volume, hence strength in the top and bottom where the bending stresses are the greatest. So holes are cut to.....reduce material?. Structurally okay because....less stresses...
  14. C

    some questions...

    1. In I-beams, why is it structurally acceptable to cut holes into the web but not into the flange? Why are holes cut? 2. A galvanized steel post is anchored to concrete by zinc cobalt coated bolts. Why are the nuts on the bolts significantly more corroded? 3. Shear Force and Bending Moments...

    Right. Time to start studying again?

    For me, I would really like to take a break but I have three assignments as well as homework from most of my subjects due over the holidays. Anyone else in this situation? but its still hooliday coz i do nothing in the evening. So i guess its just, take a break and study if you've fallen behind...

    drop or not...

    If its time, dropping IPT is 2 units while 4u is 1 unit. and maybe i will work harder with 2 less units for 4u. or is it the same, cause 4u is like 2 units worth of work?
