Can we do directly
Cos(840)
= Cos(900-60)
= -cos (60°)
= -1/2

[aryansharmaroll]

Divide 840 by 360 then remainder will be 120 the so cos(840)=cos(360*2+120).... Then cancel out of 360 along with its multiple the we get cos(120) which is can also use this process with sin cos sec cosec and for tan and cot use 180 in place of 360❤ thanks u for time

Supper teaching ur voice and teaching technic is excellent 🎉

[raginipandit]

[sandeepgsuryavamshi]

Tq mam so easy mujhe bahut difficult lag rahath thank you so much for your help

[S.k_reaction_]

Can we do directly
Cos(720+120)
Cos120
-1/2 final answer

[mythologicaleditor]

360 se minus krne se angle change nhi hota h toh -720 krenge toh cos120 is-½

[faisalabdul]

Guys simple doubt, how to know in which quadrant it lies in

[Subhan-ywtm]

we can subtract 720 from 840

answer will be same

[shivnathmahto]

thanks mam
please more videos of 11th math

[smitasatpathy]

Degree ka sign dedijye madam,
Warna sin 30 ko log radian b samjhenge, likhiyega sin 30°

[satyamkumar-wkfw]

Pahle kese jan gye ma'am ki second q.. me hai

[mrsubodh]

Mam kaise pta krenge kis quadrant me h ?

[mommyofficial]

Cos. Sin main ni change hoga sec mein change hoga
Agr ye cosec ha to sin mn hoga chnage

[misszara]

Leki dusre chaturthance mein sin plus hota h

[rinasarkar]

Mam isko to asa bhi lekha ja sakhta cos(900-60)
