Question

There is a small error. what's the error ?
integral [tan(x) = sin(x)/cos(x)]

Answer 1

@tkhunny can u solve this

Answer 2

My first impression is that the notation is meaningless. Can you formulate a better question?

Answer 3

\[\int\limits (\tan(x)) dx = \int\limits (\frac{ \sin(x) }{ \cos(x) })\]

Answer 4

@tkhunny there' error converting this integral...it is small ut what is it

Answer 5

Tough call. The little 'dx' is really superfluous if the context is properly understood. More than the 'dx' is the poor LaTeX coding, creating the scrawny parentheses on the right.

Answer 6

can iu answer it or not

Answer 7

what level math is it?

Answer 8

calculus bc

Answer 9

let me see if I understand the question.

you are saying from Tan(x) to Sin(x)/cos(x) there is a error

Answer 10

ya but there is integral on both side

Answer 11

are you missing dx in right side on purpose?

Answer 12

an error exists in the logic that says the \[\int\limits \tan x dx = \int\limits \frac{ \sin x }{ \cos x }\]. explain where and why the error occurs and provide graphical support for your explanation

Answer 13

here's the question again

Answer 14

oh there is dx on both side...MY BAD

Answer 15

well, there is constant in both function , they could be different

Answer 16

no theres not

Answer 17

no when you integrate both sides , you get

- ln|cos x| + C=? -ln{cos}+D

they are equal only when C are D equal

Answer 18

read the question i posted...the question means to ask something else

Answer 19

thts not the answer i already verified that with my teacher...answer is something else

Answer 20

ok , I don't know
