Question

$2 - \: \frac{3}{5}$
​

Answer 1

Answer:

Answer:2 - 3/5 = 5×2-3/5 = 10 - 3/5 = 7/5. ... now If $y = {tan }^{ - 1} \sqrt{ \frac{a \: cosx - b \: sinx}{b \: cosx + a \: sinx} }$find dy/dx ...

Answer 2

Answer:

$2 - \frac{3}{5}$

$\: lcm \: of \: 1 \: and \: 5 \: is \: 5$

$\frac{2 \times 5}{1 \times 5} = \frac{10}{5}$

$\frac{10 }{5 } - \frac{3}{5} = \frac{7}{5}$
