```							First of all you should be aware that, for a triangle , the property is that the sum of any two side should be greater than or equal to the third side than only a triangle can be formed. Now in ∆ABC , you can observe that.                                                                       SinC =AB/AC.   and CosC= BC/AC.     Now Sin C +Cos C= (AB+BC)/AC.      And as I told you that sum of any two side should be greater than or equal to the third side so (AB+BC)≥AC , So Sin C + Cos C is greater than or equal to 1..........Sorry for the inconvenience in the writing as the software of askIitians is not updated and so plz try to understand what I have written.. If not draw a triangle ABC and then verify my solution. Also plz approve my answer......with regards    -Darsh Payel
