Question

if m = cos α / cos β and n = cos α / sin β then m+n is equal to??

Answer 1

Answer:

Step-by-step explanation: okay cos a+ sin b= m, sin a+ cos b= m or cos^2 a+2 cos a sin b+ sin^2 b=m^2 sin a+2 sin a cos b + cos^2 b=m^2 1+2( cos a sin b+ sin a cos b)+1=m^2n^2 or 2 sin (a+b)+2= m^2+ n^2

(2 sin (a+b)= m^2+ n2-2)
