A) Finite solution
B) Infinite solution
C) One solution
D) No solution
Correct Answer: D
Solution :
\[3\cos x+4\sin x=6\] Þ \[\frac{3}{5}\cos x+\frac{4}{5}\sin x=\frac{6}{5}\] Þ \[\cos (x-\theta )=\frac{6}{5}\], \[[\text{where }\theta ={{\cos }^{-1}}(3/5)]\] So, that equation has no solution.You need to login to perform this action.
