Set x = 0 to find the value of the constant (t) in the determinant.
I’d say the expand the determinant. After writing it down, just skip a step or two and add up only the constant terms.
Maybe there’s something better than this, tho
🤦 itna simple bna diya bhaiya
Guys, just wanna ask what if we have to find p
I have three methods for it just wanna know which one do you all use
Just as supreeta said try to expand the determinant but use only the terms which give x^4 or for that matter any power of x @Gaurav_Singh11
Just wanna share replacing lamda by 1/lambda gives answer easily than that way.
No need. If you observe only x^2 term can produce an x^4 value. Therefore just evaluate the co factor of a11. See the coefficient of x^2 in the co factor. That will be the coefficient of x^4 in the given determinant.
I'm sorry for using the word coefficient everywhere😂
Yeah this is a good one too
Didn't get you ... Can you please elaborate
@Mayank_Chowdhary if you replace x by 1/x, p becomes the coefficient of the constant term
Yeah got it !
pls sir which book is that?
Allen module. And why sir?
