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

@daddydavidkapinga8846

thanks sir for simplifying this Trig expression so clearly 

much appreciated

@Broad_Muslimah

Thanku  your even better than my further maths teacher his always skipping steps and I'm such a slow learner ❤

@jfundz8076

Big respect to you sir you helped me understand this

@johnlungu2439

Very good teacher and u have really helped me

@phila3875

Thank u
You are  the best

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

@哲子仮免

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

@crazyjester993

9:41 multiplied both denominator and numerator by cosx

@princehelinsburg1933

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

@UNISHRAWAL2980

thank teacher you solve my big problem it is very hard subject for me

@kallenmudavanhu1648

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

@mmoonchild276

Easy question.  Thanks for a practice problem. Can you upload a video with harder question?

@DanoldDjikeussi

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

@SibonginkosiMoyo-z2g1v

we.appreciate this now.maths be easy
