Here you will learn proof of integration of sin inverse x or arcsin x and examples based on it.<\/p>\n

Let’s begin –<\/p>\n

Integration of Sin Inverse x<\/h2>\n
\n

The integration of sin inverse x or arcsin x is \\(xsin^{-1}x\\) + \\(\\sqrt{1 – x^2}\\) + C<\/strong><\/p>\n

Where C is the integration constant.<\/p>\n

i.e. \\(\\int\\) \\(sin^{-1}x\\) = \\(xsin^{-1}x\\) + \\(\\sqrt{1 – x^2}\\) + C<\/p>\n<\/blockquote>\n

Proof :\u00a0<\/strong><\/p>\n

\n

We have, I = \\(\\int\\) \\(sin^{-1}x\\) dx<\/p>\n

Let \\(sin^{-1}x\\) = t,<\/p>\n

Then, x = sint\u00a0<\/p>\n

\\(\\implies\\) dx = d(sin t) = cos t dt<\/p>\n

\\(\\therefore\\) I =\u00a0\\(\\int\\) \\(sin^{-1}x\\) dx<\/p>\n

\\(\\implies\\) I = \\(\\int\\) t cost dt<\/p>\n

By using integration by parts formula,<\/p>\n

I = t sin t – \\(\\int\\) 1. (sin t) dt<\/p>\n

I = t sin t – \\(\\int\\) sint dt<\/p>\n

= t sin t + cos t + C<\/p>\n

= t sin t + \\(\\sqrt{1 – sin^2 t}\\) + C<\/p>\n

Now, Put t = \\(sin^{-1}x\\) here<\/p>\n

\\(\\implies\\) I = x \\(sin^{-1}x\\) + \\(\\sqrt{1 – x^2}\\) + C<\/p>\n

Hence, \\(\\int\\) \\(sin^{-1}x\\) dx = x \\(sin^{-1}x\\) + \\(\\sqrt{1 – x^2}\\) + C<\/p>\n<\/blockquote>\n

Example<\/span><\/strong> : Evaluate \\(\\int\\) \\(x sin^{-1} x\\) dx<\/p>\n

Solution<\/strong><\/span> : We have,<\/p>\n

I = \\(\\int\\)\u00a0 \\(x sin^{-1} x\\) dx<\/p>\n

By using integration by parts formula<\/a>,<\/p>\n

I = \\(sin^{-1} x\\) \\(x^2\\over 2\\) – \\(\\int\\) \\(1\\over \\sqrt{1 – x^2}\\) \\(\\times\\) \\(x^2\\over 2\\) dx<\/p>\n

I =\u00a0 \\(x^2\\over 2\\) \\(sin^{-1} x\\) + \\(1\\over 2\\) \\(\\int\\) \\(-x^2\\over \\sqrt{1 – x^2}\\) dx<\/p>\n

= \\(x^2\\over 2\\) \\(sin^{-1} x\\) + \\(1\\over 2\\) \\(\\int\\) \\(1 – x^2 – 1\\over \\sqrt{1 – x^2}\\)\u00a0 dx<\/p>\n

= \\(x^2\\over 2\\) \\(sin^{-1} x\\) + \\(1\\over 2\\) { \\(\\int\\) \\(1 – x^2\\over \\sqrt{1 – x^2}\\) – \\(\\int\\) \\(1\\over \\sqrt{1 -x^2}\\) } dx<\/p>\n

\\(\\implies\\) I = \\(x^2\\over 2\\) \\(sin^{-1} x\\) + \\(1\\over 2\\) { \\(\\int\\) \\(\\sqrt{1 – x^2}\\) – \\(\\int\\) \\(1\\over \\sqrt{1 -x^2}\\) } dx<\/p>\n

By using integration formula<\/a> of \\(\\sqrt{a^2 – x^2}\\),<\/p>\n

\\(\\implies\\) I = \\(x^2\\over 2\\) \\(sin^{-1} x\\) + \\(1\\over 2\\) [{ \\(1\\over 2\\) \\(x\\sqrt{1 – x^2}\\) – \\(1\\over 2\\) \\(sin^{-1} x\\) } – \\(sin^{-1} x\\) ] + C<\/p>\n

\\(\\implies\\) I = \\(x^2\\over 2\\) \\(sin^{-1} x\\) +\u00a0 \\(1\\over 4\\) \\(x\\sqrt{1 – x^2}\\) – \\(1\\over 4\\) \\(sin^{-1} x\\) + C<\/p>\n
