Sir ham sab students hai aur hamare pass bank account aur net banking nhi hai toh ham sab aapka fee kaise pay kar payenge?
Aur aapne apne starting videos me kha tha ki mai gareeb bacchon ke liye videos banata hun paise ke liye nhi toh aap ab kyon paisa maang rahe hai?
Right bhai

Sir Q5. To Q10 ma formula ha like
√a^2 + x^2 = a tan x
√1 + x^2 = tan x
√a^2 - x^2 = a sin x or a cos x
√x^2 -a^2 = sec x
Till now m I not start maths bcz of net slow sir plz help my study
some student are very poor and not support by his family sir don't do as plz upload all video becz i am such in all student so plz try to understand sir and i like your way of explaining

Smooth explanation and fantastic discussion.
Thankyou sir your videos is very helpful during lockdown
U have so much of patience to explain us 🤔🙂🙂🙂👍
To phir tate pakadle 🖕🖕

Respected sir ,make correction that no one can write sin^-1x = 1/sin x. Means maths me sin^-1x = 1/sin nahi hota, aisa karna galat hai , bachcho ko marks nahi milenge. 🙏
Are you sure
Right
(Sinx)^-1=1/sinx
Thanx sir
He is right.
all was going good but paise mang kr all wasted ..!! money makes everybody greedy🖇🤦♀️

I have an alternative method which is more easy:-
Question:- tan^-1 (1/under root x^2 -1)
Solution :-
Let, x=sec theta
So, Sec^-1 x = theta
=> tan^-1 (1/ under root x^2-1)= tan^-1 (1/sec^2 theta -1)
We know that, (sec^2 theta -1) = tan^2 theta
So,
=> tan^-1 (1/ under root tan^2 theta)
Now, we will cut under root and the square
We get , tan^-1 (cot theta)
We know , tan (pi/2 - theta ) = cot theta
So,
=> tan^-1 {tan ([pi/2]- theta)}
Now cut, tan^-1 and tan
We get,
Pi/2 - theta
Now substitute the value of theta i.e. sec^-1
We get the answer as
(Pi/2)- sec^-1 x ...
Hope it helped 🙏 🙂
Smjh meto aa nhi rha help kese hoga 🤣
