Aap Sara confusion clear krti ho 🥀 tysm mam
For all those who thinks that Ex 8.3 is tought. Actually it's not that tough! Just you need clarification of concepts and need to learn all the formulas clearly. You should watch the Introduction video of this chapter properly before solving sums.
*tough
Kon kon periodic test se 1 din phale dekh raha ha😂😂😂
Mam acche se samajh agaya ab mai school se mili hui mental math or exempler solv karunga
Who thought that trigonometry was given It is difficult.. and now it seems easy.
Kuch bhi....... 😮
Bhai tu kisi or planet ka hai .Hume to samajh nahi aata trigonometry
Yes it is easy! Once you start understanding the concept and solve questions then you will find that it's not that tough!!
Mam you are a best teacher 😘😮🎉
Who take standard maths 😢
Best teacher for maths
Control and coordination
Mam has already uploaded the video of this chapter. Check it out!
Mam meh 3 baar dekh chuka pr 1 din baad fir bhul jaata kya kya krna kisme 😢
We have to practice daily to not forget
Practice is the only thing to excel in Mathematics.. Pratice everyday. Solve extra questions and try to clear your concepts properly and most importantly revise all the formulas.

22:44 doubt that there it was written cosec ² theta so can we write it as 1 + cot ²theta as cosec ² = 1 + cot ²theta but you've written it as 1/sin ² theta
nothing but you are making it complicated
@Rk._620 because hame sin cos m convert Krna thaa!
Waha par cosec h cosec ka 2 square nhi h isliye identity nhi lagegi simple rahega
Four tricks to solve :
STEP 1- convert into sin and cos
STEP 2- fractions
STEP 3- identities
STEP 4- rationalization
Mam was following first step
And you are also correct we can convert by the method you are telling but at the end we have to convert cot^2 theta into cos/sin
Thanks
Because Cosecant is reciprocal of Sine.
Mam please chapter 7 ka introduction video please mam
My comment is the first comment Aldo I am the first view
Ma'am aap ab please science ka ch 3 karwa dijiye metal and non metals

Mansi what app do u use to start your online RUclips classes ?
Mam I have one doubt that in question no.4 part 5 mai aapne 1 ko cosec²A-cot²A m change Kia but Jo upon m tha use kyu nhi kiya
Same doubt
Need nhi h denominator ko change krne ki
Because there is no need to change that. We have done that so that it becomes the same denomination so that we can cancel it out but if you will do the same with the denominator then again both will vary.
*denominator
Next ch will be human eye and colourful world plzz
Mam please start chapter electricity

Ritik sir - ( Babua OP ! ) ❤❤❤ is best
Kon kon agree karta hai like karo 👍
8.3 me aake pata chala trigo kitna hard hai😅😅😅😅😅
Actually, it's not that hard. You just need clarification of concepts and revise the formulas properly.
By Which formula we can say that sin and cos has relation?
By the First Trigonometric Idenity
Sin²A + Cos²A = 1
Hope it helps😊
Mam please statistics chapter
