If `y=cosx,y_n=(d^n(cosx))/(dx^n)` then `|(y_4,y_5,y_6),(y_7,y_8,y_9),(y_10,y_11, y_12)|=......`

If y = cos x, y_ (n) = (d ^ (n) (cos x)) / (dx ^ (n)) then det [[y_ (7), y_ (5), y_ (6) y_ ( 7), y_ (8), y_ (9) y_ (10), y_ (11), y_ (12)]] = ......

If y=cosx then find (d^(2)y)/(dx^(2)) .

If y= cos ax and y_n is n^(th) derivative of y, then |{:(y,y_1,y_2),(y_3,y_4,y_5),(y_6,y_7,y_8):}| is equal to

If y=sinx+cosx" then "(d^(2)y)/(dx^(2)) is :-

If y = cos ax, prove that | (y, y_1, y_2), (y_3, y_4, y_5), (y_6, y_7, y_8) | = 0 where y_r = d ^ r / (dx ^ r) .y

If y =sinpx and y_n is the nth derivative of y , then find the value of |{:(y,y_1,y_2),(y_3,y_4,y_5),(y_6,y_7,y_8):}|

If =sin px and y_(n) is the nth derivative of y then |(y,y_(1),y_(2)),(y_(3),y_(4),y_(5)),(y_(6),y_(7),y_(8))|=
