Find the curl of ~V<br> ~V<br> = sin(x) cos(y) tan(z) i + x^2y^2z^2 j + x^4y^4z^4 k

ch4aika [34]

Given

$\vec v = f(x,y,z)\,\vec\imath+g(x,y,z)\,\vec\jmath+h(x,y,z)\,\vec k \\\\ \vec v = \sin(x)\cos(y)\tan(z)\,\vec\imath + x^2y^2z^2\,\vec\jmath+x^4y^4z^4\,\vec k$

the curl of $\vec v$ is

$\displaystyle \nabla\times\vec v = \left(\frac{\partial h}{\partial y}-\frac{\partial g}{\partial z}\right)\,\vec\imath - \left(\frac{\partial h}{\partial x}-\frac{\partial f}{\partial z}\right)\,\vec\jmath + \left(\frac{\partial g}{\partial x}-\frac{\partial f}{\partial y}\right)\,\vec k$

$\nabla\times\vec v = \left(4x^4y^3z^4-2x^2y^2z\right)\,\vec\imath \\\\ - \left(4x^3y^4z^4-\sin(x)\cos(y)\sec^2(z)\right)\,\vec\jmath \\\\ + \left(2xy^2z^2+\sin(x)\sin(y)\tan(z)\right)\,\vec k$

$\nabla\times\vec v = \left(4x^4y^3z^4-2x^2y^2z\right)\,\vec\imath \\\\ + \left(\sin(x)\cos(y)\sec^2(z)-4x^3y^4z^4\right)\,\vec\jmath \\\\ + \left(2xy^2z^2+\sin(x)\sin(y)\tan(z)\right)\,\vec k$

A fair coin is tossed 20 times. The probability of getting the three or more heads in a row is 0.7870 and the probability of get

adelina 88 [10]

Answer:

The value is $P( H \ n \ T ) = 0.6049$

Step-by-step explanation:

From the question we are told that

The number of times is n = 20

The probability of getting three or more heads in a row is $P(H) = 0.7870$

The probability of getting three or more heads in a row or three or more tails in a row is $P(H \ u \ T ) = 0.9791$

Generally given that it is a fair coin , then $P(H) = P(T) = 0.7870$

Here P(T) is probability of getting three or more tails in a row

Generally the probability of getting three or more heads in a row and three or more tails in a row is mathematically represented as

$P( H \ n \ T ) = P(H) + P(T) - P( H \ u \ T )$

=> $P( H \ n \ T ) = 0.7870 + 0.7870 - 0.9791$

=> $P( H \ n \ T ) = 0.6049$
