    Due to some unfortunate circumstances I've had to continue this in Venoms DMS, now I can continue here.. Even though there's not much remaining

    Day 49 of commenting complex math but it gets harder each day

    Solve for x:
    log(base 2)(x^2 - 3x) > 0

    It's time to spam your profile with complex math and getting me forum banned LMAO jk <3

    Hey hey hey, it wasn't even because of this I added all staff (50) to a convo on forums, someone got depressed and banned me bcuz of it :(

    Evaluate the double integral:
    ∬(2xy + 3) dA, where the region R is bounded by x = 0, x = 1, y = 0, and y = 2.

    At this point i have no clue what any of that means

    Isn't math so fun... Like a puzzle, right? Don't you like puzzles? Mrs Venemous Lememous Man.. I've heard you love puzzles, especially ones about a myth called The Braincell Man. ;D

    Day 11 of commenting complex math but it gets harder each day

    Solve the system of equations:
    3x + 2y = 7
    x - y = 1
    terryZ_
    terryZ_
    Equation 1 (E1) = 3x + 2y = 7
    Equation 2 (E2) = x - y = 1
    E2 * 2 = 2x - 2y = 2
    Add LHS and RHS of E1 and E2 * 2
    3x + 2x + 2y - 2y = 7 + 2
    5x = 9
    x = 9/5
    Put back into E2
    9/5 - y = 1
    9/5 - 1 = y
    9/5 - 5/5 = y
    y = 4/5
    Therefore, x = 9/5, y = 4/5

    Day 10 of commenting complex math but it gets harder each day (ggs, I haven't forgotten yet...)

    Find the value of t that satisfies the equation:
    2^(3t) = 8^(t + 1)

    Congrats you made it to day 10 have a cookie

    Ikr, I haven't forgotten... yet-
    terryZ_
    terryZ_
    2^(3t) is the same as 2^(3)^(t), which is 8^(t)
    Therefore your equation would give 8^(t) = 8^(t + 1)
    t = t + 1
    Either no solution, or typo in question

    Day 9 of commenting complex math but it gets harder each day

    Evaluate the following limit:
    lim(x -> 0) [sin(x) / x]
    terryZ_
    terryZ_
    L'Hopital's rule
    lim(x->0) f(x)/g(x) = lim(x->0) f'(x)/g'(x)
    therefore lim(x -> 0) [sin(x) / x]
    = lim(x -> 0) [cos(x) / 1]
    = cos(0) / 1
    = 1

    Day 8 of commenting complex math but it gets harder each day

    Simplify the logarithmic expression:
    log(base 3)(27) + log(base 2)(8) - log(base 4)(2)

    3 + 3 - 0,5 = 5,5
