total number of integral values of 'n' so that sin x (sin x +cos x) = n has atleastone solution is-a) 2b)1c)3d)0 Share with your friends Share 3 Anuradha Sharma answered this The given equation sinxsinx+cosx=n , can be best solve by hit and trial methodFor example if we will take, x = 0 degree then n = sin0sin0+cos0=0that is a solution and again if we will take x = 45 degree then, n = sin45sin45+cos45=1212+12=1that is also a possible value of n But after this there is no other possible integral value.Hence n has 2 integeral value. -2 View Full Answer
