Question

The distance between A(cos x ,sin x) and B(-cos x,-sin x)

Answer 1

Answer:

√2

Step-by-step explanation:

Distance between (sinx,cosx) and (cosx,−sinx) is

r=

(sinx−cox)

2

+(cosx−(−sinx)

2

)

=>r=

(sin

2

x+cos

2

x−2sinxcosx)+(cox

2

x+sin

2

x−2sinxcosx)

=>r=

1+1

=>r=

2
