Throw some math problems at me or someone else

#1

the other thread is locked now, but i’m doing some advanced complex numbers and i’m not afraid of y’all so come at me

please dont hurt me

give or take a few trillion

I changed it to 93 to make it easier :wink:

-.-

the other answer

1,730,117,086,095,357,261,346,656,428,259,594,485,009,226,296,937,439,917,099,818,185,735,683,984,963,428,791,544,547,705,390,638,035,398,454,707,136,690,735,520,715,945,842,253,985,022,113,289,881,672,827,601,319,269,956,255,621,106.76117032152823229317

#9

I got 1.730117e+174 which is the same as your answer I think…
(I used the google caclulator lol)

#10

integral of 1/(root x*(1-2 root x))

#11

Solve each system by elimination

-x-6y=21
5x-12y=-21

#12

substitute x^2

#13

@Leohe

your problem:

solving:
u-sub -

thus you get

which then gives

sub u back in and get

!_!

@GGaodzilla

your problem:

-x - 6y = 21
5x - 12y = -21

solving:

-2x - 12y = 42
5x - 12y = -21
-7x = 63
x = -9
-45 - 12y = -21
-12y = 24
y = -2
y = -2 and x = -9

#14

Yeah my problem was a bit easy.
integral from 0 to pi/4 of log(1+tan x)

#15

It was the first problem of 50 in my math hw I just turned in

#16

u-sub: u = 1+tanx
du = sec2x dx
thus going back to the original equation:
erm actually never done log before, i’ll assume u mean log10

ok uhhh this is lookin bad ima just take a step outta here

int by parts:
integral of log10x is the integral of lnx/ln10 which gives ln10 * integral of lnx which is xlnx - x + C
which then gives ln10(xlnx-x+C)
w’=log10u w=ln10(ulnu-u+C)
v=1/(u-1)2 v’ = -2/(u-1)3
= ln10(ulnu-u)/(u-1)2 + 2ln10(ulnu-u+c)/(u-1)3du
i hope for my own sanity that u wrote this problem wrong .-.

#17

Doesn’t log automatically refer to ln in calculus? Also, I just google difficult calculus problems and went to the last one XD

#18

dear god lol all i know is that if i did it some other way i’d be in the realm of stackin int by parts and complex numbers and whatnot and it hurts my brain

#19

1-x=x

#20

1-x=x
1=2x
x=0.5
