Question

if Y=3÷(√19 -4) then find (y-4)^2​

Answer 1

Answer:

We have y = Asinx + Bcosx ⇒ y1 = Acosx – Bsinx ⇒ y2 = –Asinx – Bcosx = –y ⇒ y2 + y = 0 By Leibnitz theorem, we get, ⇒ yn+2 + (0)yn+1 + (0) yn + yn = 0 ⇒ yn+2 + yn = 0Read more on Sarthaks.com - https://www.sarthaks.com/536436/if-y-asinx-bcos-x-then-prove-that-i-y2-y-0-ii-yn-2-yn-0?show=536439#a536439

Answer 2

Answer:

Hey mate here is the answer

Step-by-step explanation:

ANSWER IS (19)

check out the answer below

By rationalising Y

We get Y= √19+4

Now substitution of Y in the equation given

(√19+4-4)^2

(√19)^2

= 19
