GrogVix [38]

Answer:

(\frac{dy}{dt})^2=sin^2t

Step-by-step explanation:

y=cost

DE :(\frac{dy}{dt})^2=1-y^2

If y is a solution of given DE then it satisfied the DE.

Differentiate w.r.t t

\frac{dy}{dt}=-sint

Using the formula

\frac{d(cosx)}{dx}=-sinx

LHS:(\frac{dy}{dt})^2=(-sint)^2=sin^2t

RHS

1-y^2=1-cos^2t=sin^2t

By using the formula

sin^2t=1-cos^2t

LHS=RHs

Hence, y is a solution of given DE

(\frac{dy}{dt})^2=sin^2t

Which two values of x are roots of the polynomial below?<br> 5x2 - 5x+1
Natalija [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

5 {x}^{2}  - 5x + 1 = 0

(x -  \frac{5 +  \sqrt{5} }{10} )(x -  \frac{5 -  \sqrt{5} }{10} ) = 0 \\

Thus :

x =  \frac{5 + \sqrt{5} }{10}  \\

x =  \frac{5 -  \sqrt{5} }{10}  \\
