why sin(-θ) = -sin(θ)
cos(-θ) = cos(θ)
tan(-θ) = -tan(θ)
cot(-θ) = -cot(θ)
sec(-θ) = sec(θ)

cosec(-θ) = -cosec(θ)
sin(90-θ) = cosθ, cos(90-θ) = sinθ, tan(90-θ) = cotθ

Wah !!! Eise math class start ho to maja hi ajaye 😄

[DurgaPrasad-kdyu]

Wahh !!!
Class is very interesting.
With very beautiful song.
😄😄

Sir mujhe is video ke proof ki talash Sab aaye or Bina proof ke sirf ratwa ke chale Gaye....lekin aapne proof Diya or kaafi achha samjhaya to sab samajh aa Gaya
Thankyou sir

[shikadasshika]

Thanks sir....
Aj mein properly

[saikanade]

thank you very much sir I was trying to find the proof of this sin (90+x)=cosx from so long time, now i have understand everything you genius teacher ✨✨✨✨

[mohdhasan]

Thenque sir . Sab logo ne ratta lagvaaya aapne bataya . Then que sir u r great 😍🤗

[juhita]

Sir apne Bohot acche se samjhaya iske liye thank you sir
