Answer:
yes
Step-by-step explanation:
We are given that a Cauchy Euler's equation
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}](https://tex.z-dn.net/?f=w%28x%29%3D%5Cbegin%7Bvmatrix%7Dy_1%26y_2%5C%5Cy%27_1%26y%27_2%5Cend%7Bvmatrix%7D)
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](https://tex.z-dn.net/?f=y_1%3Dt%2Cy_2%3Dt%20ln%20t)
![y'_1=1,y'_2=lnt+1](https://tex.z-dn.net/?f=y%27_1%3D1%2Cy%27_2%3Dlnt%2B1)
![w(x)=\begin{vmatrix}t&t lnt\\1&lnt+1\end{vmatrix}](https://tex.z-dn.net/?f=w%28x%29%3D%5Cbegin%7Bvmatrix%7Dt%26t%20lnt%5C%5C1%26lnt%2B1%5Cend%7Bvmatrix%7D)
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.
25% of 15 is the same as 15% of 25
25%=25/100
25% of 15=(25/100)15=(25*15)/100
15%=15/100
15% of 25=(15/100)25=(25*15)/100
Therefore:
25% of 15=15% of 25
because:
(25/100)15=(15/100)25
(25*15)/100=(25*15)/100
3.75=3.75
Measure of angle b= 27°
It’s a right angle, so 90-63=27!!!!!
Your equation: 4x² - 100 = 0
Factor the left side: (2x + 10) · (2x - 10) = 0
This equation is true if either factor is zero.
-- One factor: 2x + 10 = 0
Divide each side by 2: x + 5 = 0
Subtract 5 from each side: x = -5 .
-- The other factor: 2x - 10 = 0
Divide each side by 2: x + 5 = 0
Add 5 to each side: x = 5 .
