If` acostheta+ bsintantheta=3` and `asintheta-bcostheta = 4,` then `a^2 + b^2` has the value

If a costheta + b sintheta=3 and a sintheta - b costheta=4 , then a^(2)+b^(2) has the value 25

If a costheta + b sintheta=3 and a sintheta - b costheta=4 , then a^(2)+b^(2) has the value 25

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

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

Answer each question by selecting the proper alternative from those given below each question so as to make each statement true : If acostheta+bsintheta=4 and asintheta-bcostheta=3 , then a^(2)+b^(2) =…..

If acostheta+bsintheta=m and asintheta-bcostheta=n , then a^2+b^2= (a) m^2-n^2 (b) m^2n^2 (c) n^2-m^2 (d) m^2+n^2

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