Question

d/dx(cos(x)^1/2)^1/2=? please don't give irrevealeant answers ​

Answer 1

Answer:

$d \: cos \: \alpha + d \sin( \beta ) + log( \gamma ) = \sqrt{5}$

Answer 2

$y = cos { - }^{1} (2 { x}^{2} - 1)z = cos { - }^{1} x$

$\frac{dy}{dz} = \frac{dy \div dx}{dz \div dx}$

$y = cos { - }^{1} (2 {x}^{2} - 1)$

$\frac{dy}{dx} = \frac{ - 1}{ \sqrt{1 - 2 {x}^{2} - 1) = (4x - 0)$

solve this equation

then answer is 2

hope it helps you
