Question

Find the distance between two points (xcosθ + ysinθ, 0) and (0, xsinθ - ycosθ).

Answer 1

Step-by-step explanation:

√((x"-x')^2+(y"-y')^2)

√((0-(xcos@+ysin@))^2+(xsin@-ycos@-0)^2)

√(x^2cos^2@+y^2sin^2@+2xysin@cos@+x^2sin^2@+y^2cos^2@-2xysin@cos@)

√(x^2(cos^2@+sin^2@)+y^2(cos^2@+sin^2@))

√(x^2+y^2)
