1.	Find the distance between the points `( acostheta, asintheta) ` from the origin.
Answer» Distance between the points `( acostheta, asintheta) ` and origin (0, 0) ` " "=sqrt((acostheta-0 )^(2)+(asintheta-0)^(2))` `" "=sqrt (a^(2)cos^(2)theta+a^(2)sin^(2)theta)=sqrt(a^(2) (cos^(2)theta+sin^(2)theta)) ` `" "=sqrt(a^(2))` `" "=a" units"" "(because cos^(2)theta+sin^(2)theta=1)`
