Does the set {t, t Int} form a fundamental set of solutions for t^2y" -- ty' +y = 0?
Ivanshal [37]

Answer:

yes

Step-by-step explanation:

We are given that a Cauchy Euler's equation

t^2y''-ty'+y=0 where t is not equal to zero

We are given that two solutions of given Cauchy Euler's equation are t,t ln t

We have to find  the solutions are independent or dependent.

To find  the solutions are independent or dependent we use wronskain

w(x)=\begin{vmatrix}y_1&y_2\\y'_1&y'_2\end{vmatrix}

If wrosnkian is not equal to zero then solutions are dependent and if wronskian is zero then the set of solution is independent.

Let y_1=t,y_2=t ln t

y'_1=1,y'_2=lnt+1

w(x)=\begin{vmatrix}t&t lnt\\1&lnt+1\end{vmatrix}

w(x)=t(lnt+1)-tlnt=tlnt+t-tlnt=t where t is not equal to zero.

Hence,the wronskian  is not equal to zero .Therefore, the set of solutions is independent.

Hence, the set {t , tln t} form a fundamental set of solutions for given equation.

What are the sine cosine and tangent of theta=7pi/4 radians
FrozenT [24]

Answer:

see explanation

Step-by-step explanation:

\frac{7\pi }{4} is in the fourth quadrant

Where sin and tan are < 0 , cos > 0

The related acute angle is 2π - \frac{7\pi }{4} = \frac{\pi }{4}

Hence

sin([\frac{7\pi }{4} ) = - sin(\frac{\pi }{4}) = - \frac{1}{\sqrt{2} } = - \frac{\sqrt{2} }{2}

cos(\frac{7\pi }{4}) = cos(\frac{\pi }{4}) =  \frac{\sqrt{2} }{2}

tan(\frac{7\pi }{4}= - tan(\frac{\pi }{4} = - 1
