What is the distance between the points A (Sin theta- Cos theta,0 ) and B(0,Sin theta+Cos theta)? |
| Answer» = whole root (0 - sin theta + cos theta)^2 + (sin theta + cos theta - 0)^2 = whole root sin ^2 theta + cos^2 theta + sin ^2 theta + cos ^2 theta = whole root 2sin ^2 theta + 2cos ^2 theta= whole root 2(sin ^2 theta + cos ^2 theta )= whole root 2(1) [since sin^2 theta + cos^2 theta =1]= therefore root 2Distance is root 2 | |
