Trigonometric Identity Proof - example test question

[@umapatil6813]

Do the students realise how lucky they are ?..(exited, polite tone)
I would be soo glad if I could attend his classes.

Sir You are the best
You are great teacher of maths who makes maths a game😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍

8:24 the reciprocal trig functions are also on the reference sheet in the same heading as the Pythagorean identity "trigonometric identities"

First view, like and comment. You’re inspiration!

[@SteveHeller19]

splitting the first fraction simplifies just as quickly! After all, it splits 1/sin from the left which matches the form on the right.

Nice video
Love from india

I'm in 11th grade and studying maths but idk why these students are getting shocked with this trigonometry proof like our teacher never told us cross multifunction and fractions solving, this is understood. 😳

Same bro I am in class 10 and this is like from NCERT I GUESS

[@nezz0r]

I solved it like this:
(1 + cosQ) / sinQ + sinQ / (1 + cosQ) = 2cosecQ
LHS:
(1 + cosQ) / sinQ + sinQ / (1 + cosQ)
First change the second term a bit because (1 + cosQ) looks quite nice to work with.
(1 + cosQ) / sinQ + sinQ * (1 - cosQ) / ((1 + cosQ) * (1 - cosQ))
(1 + cosQ) / sinQ + sinQ * (1 - cosQ) / (1 - (cosQ)^2) --> identity: (sinQ)^2 = 1 - (cosQ)^2
(1 + cosQ) / sinQ + sinQ * (1 - cosQ) / (sinQ)^2 --> work on the fraction
(1 + cosQ) / sinQ + (1 - cosQ)/ sinQ --> Now we can put them both on the same nominator.
(1 + cosQ + 1 - cosQ) / sinQ
2/sinQ ---> Identity cosecQ = 1 / sinQ
2cosecQ = RHS

Why are u solving class 10th q

[@Drforeverok]

Imagine if every teacher had ur ability, my goodness 😀

[@soheelmahmoodsagri2823]

That was very easy..

[@elee2968]

Trig proofs...my fav 😍😍
They’re like puzzles

[@shreyasp3287]

How are you doing them now

[@amrutdeshpande5565]

🥰

[@atharvasharma3492]

Getting vibes of CBSE class 10 in India

[@anjalibisht8100]

This is for which grade?

[@sanialam6185]

Listening from Bangladesh

[@JoshuaLokz]

5:24 how come no need square theeta?

[@silaspoulson9935]

sin^2 x === (sin x) ^2 is just how you write it - it's not (sin x^2)^2 which would need theta squared

[@rohitagarwal9932]

which standard class is this

[@atharvasharma3492]

This was 10th in India but idk in Australia

[@jcn268]

im no where near college, but i learnt cos(0)+sin(0) is 1.

[@asurp7173]

XD

[@atharvasharma3492]

Learn this cos^2A+sin^2A=1

[@krsteanjoseph5351]

4th

[@nanimuwu]

Yooooooo

[@vitaminprotein6859]

This is literally nothing for class 9 students in indian they are gonna solve this in just 30 seconds😂🙏

[@Drforeverok]

They are fuddus
