  What is the integral of the function f(x) = 6x^3 - 4x^2 + 2x - 10 with respect to x?

  To find the integral of the function ( f(x) = 6x^3 - 4x^2 + 2x - 10 ) with respect to ( x ), we integrate each term of the polynomial separately:

  1. The integral of ( 6x^3 ) is ( \frac{6}{4}x^4 = \frac{3}{2}x^4 ).
  2. The integral of ( -4x^2 ) is ( \frac{-4}{3}x^3 = -\frac{4}{3}x^3 ).
  3. The integral of ( 2x ) is ( \frac{2}{2}x^2 = x^2 ).
  4. The integral of ( -10 ) is ( -10x ).

  Combining these results, the integral of the function is:

  [ \int (6x^3 - 4x^2 + 2x - 10) , dx = \frac{3}{2}x^4 - \frac{4}{3}x^3 + x^2 - 10x + C ]

  where ( C ) is the constant of integration.

  What is the derivative of the function g(x) = x^5 - 3x^3 + 7x - 4 with respect to x?

  To find the derivative of the function ( g(x) = x^5 - 3x^3 + 7x - 4 ) with respect to ( x ), we can apply the power rule of differentiation. The power rule states that the derivative of ( x^n ) is ( nx^{n-1} ).

  Let's differentiate each term of the function:

  1. The derivative of ( x^5 ) is ( 5x^4 ).
  2. The derivative of ( -3x^3 ) is ( -9x^2 ).
  3. The derivative of ( 7x ) is ( 7 ).
  4. The derivative of the constant ( -4 ) is ( 0 ).

  Putting it all together, the derivative ( g'(x) ) is:

  [ g'(x) = 5x^4 - 9x^2 + 7 ]

  So, the derivative of the function ( g(x) = x^5 - 3x^3 + 7x - 4 ) with respect to ( x ) is ( 5x^4 - 9x^2 + 7 ).

  What are the eigenvalues of the matrix A = [[4, 1], [2, 3]]?

  To find the eigenvalues of a matrix, we need to solve the characteristic equation, which is derived from the determinant of the matrix ( A - \lambda I ), where ( \lambda ) is the eigenvalue and ( I ) is the identity matrix.

  For the matrix ( A = \begin{bmatrix} 4 & 1 \ 2 & 3 \end{bmatrix} ), the characteristic equation is:

  [ \text{det}(A - \lambda I) = \text{det}\left(\begin{bmatrix} 4 - \lambda & 1 \ 2 & 3 - \lambda \end{bmatrix}\right) = 0 ]

  The determinant of a 2x2 matrix (\begin{bmatrix} a & b \ c & d \end{bmatrix}) is calculated as ( ad - bc ).

  Let's calculate the determinant:

  [ (4 - \lambda)(3 - \lambda) - (1)(2) = 0 ]

  This simplifies to:

  [ (4 - \lambda)(3 - \lambda) - 2 = 0 ]

  Expanding the terms:

  [ (4 - \lambda)(3 - \lambda) = 12 - 4\lambda - 3\lambda + \lambda^2 = \lambda^2 - 7\lambda + 12 ]

  So the equation becomes:

  [ \lambda^2 - 7\lambda + 12 - 2 = 0 ]

  [ \lambda^2 - 7\lambda + 10 = 0 ]

  Now, we need to solve this quadratic equation for (\lambda). I will calculate the roots of this equation to find the eigenvalues. It seems there was an error when trying to directly calculate the roots of the quadratic equation. Instead, let's manually solve the quadratic equation ( \lambda^2 - 7\lambda + 10 = 0 ) using the quadratic formula:

  [ \lambda = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ]

  Here, ( a = 1 ), ( b = -7 ), and ( c = 10 ).

  Let's calculate the discriminant ( b^2 - 4ac ):

  [ (-7)^2 - 4 \cdot 1 \cdot 10 = 49 - 40 = 9 ]

  Now, we can apply the quadratic formula:

  [ \lambda = \frac{7 \pm \sqrt{9}}{2 \cdot 1} = \frac{7 \pm 3}{2} ]

  This gives us two possible eigenvalues:

  1. ( \lambda_1 = \frac{7 + 3}{2} = \frac{10}{2} = 5 )
  2. ( \lambda_2 = \frac{7 - 3}{2} = \frac{4}{2} = 2 )

  Thus, the eigenvalues of the matrix ( A = \begin{bmatrix} 4 & 1 \ 2 & 3 \end{bmatrix} ) are ( \lambda_1 = 5 ) and ( \lambda_2 = 2 ).

  What is the Taylor series expansion of f(x) = e^x around x = 0 up to the fourth degree term?

  The Taylor series expansion of a function ( f(x) ) around ( x = 0 ) (also known as the Maclaurin series) is given by:

  [ f(x) = f(0) + f'(0)x + \frac{f''(0)}{2!}x^2 + \frac{f'''(0)}{3!}x^3 + \frac{f^{(4)}(0)}{4!}x^4 + \cdots ]

  For the function ( f(x) = e^x ), all derivatives of ( e^x ) are ( e^x ), and at ( x = 0 ), they all evaluate to 1. Therefore, the Taylor series expansion of ( e^x ) around ( x = 0 ) up to the fourth degree term is:

  [ e^x \approx 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \frac{x^4}{4!} ]

  Calculating the coefficients:

  • ( \frac{x^2}{2!} = \frac{x^2}{2} )
  • ( \frac{x^3}{3!} = \frac{x^3}{6} )
  • ( \frac{x^4}{4!} = \frac{x^4}{24} )

  Thus, the expansion is:

  [ e^x \approx 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \frac{x^4}{24} ]

  This is the Taylor series expansion of ( e^x ) around ( x = 0 ) up to the fourth degree term.

  What is the Fourier transform of the function f(t) = e^{-t^2}?

  The Fourier transform of the function ( f(t) = e^{-t^2} ) is a well-known result in mathematics. This function is a Gaussian function, and its Fourier transform is also a Gaussian function.

  The Fourier transform of ( f(t) = e^{-t^2} ) is given by:

  [ F(\omega) = \sqrt{\pi} e^{-\frac{\omega^2}{4}} ]

  This result is derived from the properties of the Gaussian function and the Fourier transform. The Gaussian function is unique in that its Fourier transform is also a Gaussian, and the width of the Gaussian in the frequency domain is inversely proportional to the width in the time domain.
