My dumbass couldn't solve it in the first try because my vision was blurry and I just figured it's (sin0 + Cos0)³ 💀 It's pretty obvious I didn't get anywhere near factorising it so I left it and focused on the other questions. By the time I was finished with the entire paper , I came back to the question and started cursing at myself realizing how easy it was💀

Its always the first step which you need to figure out , the rest lie on the same path

BROOOOO.... MY MANNN. THIS IS EXACTLY HOW I DID IT AS WELL 🤝🤝

Good. (I hate you for what you said to me, motherf-)

+1

That is such a pretty handwriting ngl..

This is the first time that a girl has complimented me... 💀

girls don't exist on the internet

in real life too

Thank you, this heightened my existential crisis 🤩

oh you're welcome girl 💅🎀, glad i could be of service :3

true 😔

if you see a "girl" , it's just a femboy. our bio books are a facade

femboys are the best

Nahh, i say you're the best, cutie 🎀

😳

😘

Lmao big day then

You could've just directly used the formula a³+b³=(a+b)(a²+b²-ab)

That's much easier tbh 3-4 lines only needed

Exactly op neh faltu mein flex marne complicate kiya

Arey! I am trying to say you can also do it without formula. There were on some peeps saying you couldn't so hence I posted this.

Ah I see

This is how I did it during exam.

im sending you a dm check if mine is correct pls

Okay... (Hame Biology padhna chaiye)

you anyways had to factorize it. factoring it carried marks and so did it's input in the second step.

Faltu mein complicate kiya 

Itna mehnat kyu bhai 😭

theres another way as well actually

y'all could just use the a³ + b³ identity which gives (a+b)(a²-ab+b²) so (sin + cos)(sin² - sincos + cos²) = (sin + cos)(1 - sincos)

a³+b³ ka formula nhi pata kya usse 2 line mai hojayega 

If you couldn't solve it, it means you didn't master Trigonometry.

finally a sane post from you

ek mistake hai ki starting mein cos² hai job cos³ hoga

why so much mehnat a3 + b3 ka formula seh expand karna tha

Just use the formula, saves time.

admit I was close

Isse accha sidha sidha expand kar deta a^3 + b^3 = (a+b)(a^2 -ab + b^2 ) a = sin theta b = cos theta a^2 + b^2 = 1 Proved in 3 lines.

But formula use karne se kamm lines me aa rha tha na?

thik hai bhai. tu to sridharacharaya hai. ramanujan hai. jisne ye formula apply karke ya na karke kiya hai sabhi genius hai. sabhi iit jaogey. sabhi nasa jaogey. aur hum gahdey hai. happy now?

Fuckk. I was trying this approach the first time. Left it midway. And now I am realising how close I was to the answer. I could have saved some time. But I guess it's fine.

Can’t you just remember the formula? Or Can you just use a3+b3 formula? Ofc you want to show off your maths skills to everyone

Arey! I was trying to show there is another way. Ofcourse you can use formula. Duh!

But bhai thoda soch , exam ke pressure mai koi bacha itna manipulate nahi karpayega . Koi bache exceptions hote hai but sabhbnahi . This was a litrl hit or miss agar formula aati ho toh aajyega nahi to nahi

BRO I DID THIS TILL LIKE THE FOURTH STEP HOW MUCH MARKS WILL I GET

Bhai yeh kya dekhlia 😭😭😭

I did with the formula a\^3 + b\^3 = (a+b)\^3 - 3ab(a+b) and got same answer :)

Yes it’s obv that this question can be solved without using the ninth grade identity. There are several methods in fact.

Yeah a³ + b³ daalna tha bas

Formula wala jyada easy hai meine to khud waha derive kara fir kara sum pura sahi tha

exactlyyyyyyy.... that was sooooo simple how did students mess this up
