Question

Please integrate this
$\frac{1}{\sqrt{x} } \sin( \sqrt{x} )dx \: integrate \: it \: please$
​

Answer 1

{$ > integration sign In this explanation}

• Let sqrt{x} be t
• differentiating both sides
• 1/ 2.sqrt{x} d(x) = d(t)
• 1/ sqrt{x} d(x) = 2d(t)

Putting this value in the given equation -

• 2$ sin(t) d(t)
• 2( -cos(t))
• -2(cos(sqrt{x})

That's the answer mate.

Hope it helps :)
