I got the answer but need to confirm if it's right

  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

use \frac12 for the fraction

#

$\int \frac{\tan x}{(\sin^4x + \cos^4 x)^{\frac12}}dx$

#

looks terrible but hey i don’t do formatting

#

Yea this

#

send your solution

Can ya verify it for me?

#

,w integrate tan(x)/(sin^4(x)+cos^4(x))^(1/2)

#

well, they look different

#

This is the solution given by my teacher which ig is wrong

#

I need some verification on my answer in order to argue with my teacher about this

#

Can it show more forms of the answer?

#

ok, do you have a solution

#

as in, working out steps

spice tendon
#

I can do it again though

#

@spice tendon

#

are you using u = tanx or u=tan^2x

spice tendon
#

The second substitution needs a diff variable my bad

#

Assume v or smth pls

#

oh, you calculated du/dx using another chain rule

#

right

#

i mean, you missed the 1/2

#

A better version

spice tendon
spice tendon
#

what

#

I'm gonna write it down

#

@spice tendon

#

i feel like all there’s left to do is procure a copy of your teacher’s solution and find exactly what went wrong

spice tendon
#

So gotta talk to them about it ig

#

@spice tendondid u divide by cos^4

#

caus that prolly works

spice tendon
#

I tried a bunch of stuff before that

spice tendon
spice tendon
spice tendon
#

it confusingg

spice tendon
#

did u divide by cos^4 or cos^2

#

?

#

@spice tendon]

spice tendon
#

okay

#

so when u do that

#

how do u get root tan^4 x +1

spice tendon
spice tendon
#

in the question which u postrd

#

at start

spice tendon
#

I didn't know the latex stuff

#

okay

#

ykw

#

is this from ncert

#

?

#

also there might be another approach to it

#

u can probably take cos^4 common from inside the root

#

so outside comes cos^2

#

which goes up and becomes sec

#

then take tan x = t so u get t / root 1+t^2

#

@spice tendon

#

so like theres TWO phases of this question

#

and two methods to do each of em

#

pretty cool

spice tendon
#

so what was ur question again

#

u wanna confirm ur answe?R

#

He found it quite challenging so he gave it to us

spice tendon
spice tendon
#

why did u give your answer in theta

#

It's X

#

yeah

#

I mistook it ig

#

hm

spice tendon
spice tendon
#

I found it quite easy ngl

spice tendon
#

u can try it if u want

#

i do know the answer nw

#

Where are they?

#

Helo school?
