The distance between the points `(acostheta+bsintheta,0)a n d(0, asintheta-bcostheta)` is `a^2+b^2` (b) `a+b` `a^2-b^2` (d) `sqrt(a^2+b^2)`

The distance between the points (a cos theta+b sin theta,0) and (0,a sin theta-b cos theta) is a^(2)+b^(2)(b)a+ba^(2)-b^(2)(d)sqrt(a^(2)+b^(2))

(a) a^2+b^2 (b) a+b (c) a^2-b^2 (d) sqrt(a^2+b^2)

If acosheta+bsintheta=4 & asintheta - bcostheta= 3 then a^2+b^2

If acostheta+b sintheta=x and asintheta-bcostheta=y prove that a^2+b^2=x^2+y^2

If acostheta+bsintheta=m and asintheta-bcostheta=n , prove that a^2+b^2=m^2+n^2

If acostheta+bsintheta=m and asintheta-bcostheta=n , Prove that a^2+b^2=m^2+n^2

x/acostheta+y/bsintheta=1, x/asintheta-y/bcostheta=1 then x^2/a^2+y^2/b^2=

x/acostheta+y/bsintheta=1, x/asintheta-y/bcostheta=1 then x^2/a^2+y^2/b^2=

If acostheta+bsintheta=4 and asintheta-bcostheta=3 , then a^2+b^2 = (a) 7 (b) 12 (c) 25 (d) None of these

If acostheta-bsintheta=c , then asintheta+bcostheta= (a) +-sqrt(a^2+b^2+c^2) (b) +-sqrt(a^2+b^2-c^2) (c) +-sqrt(c^2-a^2-b^2) (d) None of these
