Question

The distance between the points in (acosalpha,0) and (0,asinalpha) is​

Answer 1

Answer:

a

Step-by-step explanation:

Distance between two points is given by √((x1- x2)²+(y1-y2)²). Therefore distance between the points is given by, d = √{(acosalpha)-0)²+(0- (asinalpha))² = √a²(cos²alpha +sin²alpha) = a

Answer 2

Step-by-step explanation:

√(x2-x1)² +(y2-y1)²

√(0-a cosalpha)²+(a sinalpha-0)²

√(a cos²alpha+a sin²alpha)

√(a²(cos²alpha + sin²alpha)

√a²×1

√a²

`|a| or +-a. answer
