Question

Que for physics lovers

Answer 1

Answer:

the range of equation

asin¢+bcos¢ +c

is from

$c - \sqrt{ {a}^{2} + {b}^{2} } to \: c + \sqrt{ {a}^{2} + {b}^{2} }$

here a=1 and b=1 and c=o

let sin¢ +cos¢ =x

so the range of sin¢+cos¢= -√2 to +√2

here y=4/x

y to be minimum x should be maximum

so maximum value of x=√2

y=4/√2=2√2

UR answer is 2√2
