Question

where's the math palette? What if I want the integral sign?

Answer 1

integral(f(x)) from [a,b] if anything

Answer 2

but in here we got the equation button that has it in it

Answer 3

if you know how to type in LaTeX coding then you can type it in directly

Answer 4

\[\huge\int xdx\]

Answer 5

\int x^2dx

Answer 6

\ followed by [ and then by \] with your equation stuff in betwee

Answer 7

\int \frac{x+1}{x-1}dx

Answer 8

\[\int x^2\ dx\]

Answer 9

youve got the innards good; but you gotta tell the reply box that its actually in latex code by wrapping it in \ and [ and \ and ]

Answer 10

what is \int \frac{x+1}{x-1}dx

Answer 11

\[\int \frac{x+1}{x-1}dx\]

Answer 12

\int {\frac{x+1}{x-1}}dx

Answer 13

This is more strict than regular LaTeX

Answer 14

\[\int stuff \*]
^ remove the *

Answer 15

it is becasue the text is parsed and you have to encode it in the delimiters

Answer 16

Yeah ok, thank you!

Answer 17

but to answer; you might wanna seperate it up into seperate fractions:

\[\int\frac{x}{x-1}+\frac{1}{x-1}dx\]

Answer 18

then int by parts the left side there

Answer 19

+x(ln(x-1))
-1(integral of ln(x-1))? :)

Answer 20

or \[\int\frac{x+1}{x-1}dx=\int\frac{x-1+2}{x-1}dx=\int\frac{x-1}{x-1}dx+\int\frac{2}{x-1}dx=\int 1dx+\int\frac{2}{x-1}dx\]

Answer 21

yeah, that does seem easier :)

Answer 22

i tend to forget about adding zero ....

Answer 23

best tricks...add '0' and multiply by '1'
