അതിൽ schemes ഇപ്പോഴത്തെ സിലബസിൽ ഇല്ല. പിന്നെ കറന്റ് അഫയേഴ്സ് ഒരുപാട് പഴയതും ഒഴിബാക്കി.. സയൻസ്, IT അതിന്റെ കോഴ്സിൽ ഇടുന്നുണ്ട്. GK മാത്രം ഇതിൽ. 👍👍

No the answer will be same whether you take the angle as CW or ACW

Don't forget to take square of the cos.... Silly might happen
For 2nd solution: Since you have taken all the angles in ACW sense then why you have takn the K Cos 75 in CW sense. Though the answer would be same but it must be K Cos 285 in place of K Cos 75..
