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

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

nordsb [41]

Answer:

see explanation

Step-by-step explanation:

(a)

AB = AO + OB = - a + b = b - a

(b)

OP = OA + AP = a + $\frac{3}{4}$ (b - a ) = a + $\frac{3}{4}$ b - $\frac{3}{4}$ a = $\frac{1}{4}$ a - $\frac{3}{4}$ b
