thanks sir for simplifying this Trig expression so clearly

much appreciated

[jfundz]

Big respect to you sir you helped me understand this

[Augustus]

Use double angle formula and divided 2cos ^2x by both top and base, and simplify it. Just need 3 step. (2tanx-sin2x)/2sin²x=(tanx(1+tan²x)-tanx)/tan²x=tanx, and x≠kπ, π/2+kπ which k∈Z

[pritamshahi-mlvw]

Because there are many formulas with the trigonometric functions I am trying to prove, I don’t know which formula to use.

I appreciate you great teacher 👏👏👍👍🙏🙏💯💯

[johnlungu]

Very good teacher and u have really helped me

[mazwuzulu]

Please write my exam for me . You smart Dude

[princehelinsburg]

thankx for well explained solutions, i need help how do i solve this tanh2x=2tanhx/1+tanh^2 x. (1+tan hsquared x)

[crazyjester]

9:41 multiplied both denominator and numerator by cosx

[kallenmudavanhu]

Good job. Which board and tools are you using to write?

[vexqcfo]

Thanks. I got it now how to prove trig identities so easily.

[tebogomagz]

There's several ways to do it. Just choose the one that makes sense to you ❤

[ofzbhys]

It's helpful but I can't apply it

[ShahaduIshak-pect]

Please sir I did understand why the sin cancel the square

[etlrcdc]

Sir I noticed you pronounced sin as sin
Pls it is pronounced /sain/
Thank you

[DanoldDjikeussi]

I think the main problem in trigonometry is the identities and not the solving😊

[KingdomEjiro]

Sir pls I want you to solve something for me

[cxcydzy]

U made a mistake with the common denominator

[shahedabegum]

I'm just 5th grade:):3its very hard

[cattt]

Im just 14 what did i do to deserve this
