@Aman
LH rule?
Yup
I'm assuming the limit exists
How
L'Hôpital Rule
Differentiate numerator and denominator separately.
Can u tell me
Just a sec. I'll take a pic.
@Aman sorry, got delayed
Idts even series expansion would help like
root(tanx) binomial approx+series of tanx
Try to rationalise everything
dealing with this in terms of tan^2 and cos^2 terms would be easier
Hence we multiply and divide by (tanx -2 -sqrt tanx)
also (2sinx + sqrt 2)
After that, you’re one step away from the answer
I rationalised it but i got too many terms after 2step
Thanks
