Expert Answer:

Dear Student
The given statement is false
The maximum value of acos x + bsin x + c is given as c + square root of (a² + b²) .

Consider given expression 2sinx+3cosx
Here a =2 b=3 and c =0

So Maximum value =  square root of (2² + 3²)
=square root of 13 which is less than 10
So this equation2sinx+3cosx=10 does not have any soultion
