यदि y = 2 sin x + 3 cos x, तो y_(2) बराबर है : | 12 | अवकलन | MATHS | SHIVLAAL PUBLICATION | D...

If y= sin x+cos x then (d^(2)y)/(dx^(2)) is :-

If y=sin3x cos5x, then (d^(2)y)/(dx^(2))=?

If y=2sin x+3cos x, show that (d^(2)y)/(dx^(2))+y=0

If y=2sin x+3cos x, show that (d^(2)y)/(dx^(2))+y=0

x= 2 cos t -cos 2t ,y=2 sin t-sin 2t Find d y / d x

x = cos A + cos2A + cos3A, y = sin A + sin2A + sin3A rArr (x) / (y)

Solution of differential equation (2x cos y + y ^ (2) cos x) dx (2y sin xx ^ (2) sin y) dx = 0 is (a) x ^ (2) cos y + y ^ (2) sin x = C (b) x cos yy sin x = C (c) x ^ (2) cos ^ (2) y + y ^ (2) sin ^ (2) x = C (d) x cos y + y sin x = C

(sin 2x - sin 2y)/(cos 2y-cos 2x) = cot (x+y)

If y =5 cos x -3 sin x," then " (d^(2)y)/(dx^(2)) is equal to :
