begin mathsize 16px style straight I equals integral sin to the power of negative 1 end exponent square root of fraction numerator straight x over denominator straight a plus straight x end fraction end root dx
straight x equals atan squared straight t
rightwards double arrow dx equals straight a open parentheses 2 tantsec squared straight t close parentheses dt
straight I equals integral sin to the power of negative 1 end exponent square root of fraction numerator straight a tan squared straight t over denominator straight a plus straight a tan squared straight t end fraction end root straight a open parentheses 2 tantsec squared straight t close parentheses dt
straight I equals integral sin to the power of negative 1 end exponent square root of fraction numerator tan squared straight t over denominator 1 plus tan squared straight t end fraction end root straight a open parentheses 2 tantsec squared straight t close parentheses dt
straight I equals integral sin to the power of negative 1 end exponent square root of fraction numerator tan squared straight t over denominator sec squared straight t end fraction end root straight a open parentheses 2 tantsec squared straight t close parentheses dt
straight I equals 2 straight a integral sin to the power of negative 1 end exponent open parentheses sint close parentheses tant open parentheses 1 plus tan squared straight t close parentheses dt
straight I equals 2 straight a integral straight t space tant open parentheses 1 plus tan squared straight t close parentheses dt
