Question

find the derivative of function w r t the respective independent variable. q=square root of 2r - (r) square, find dq/dr?

Answer 1

[tex]q= \sqrt{2r- r^{2} } \frac{dq}{dr} = \frac{1}{2 \sqrt{2r- r^{2} } } . \frac{d(2r- r^{2}) }{dq} \frac{dq}{dr} = \frac{1}{2 \sqrt{2r- r^{2} } }. ( 2-2r)[/tex]
