InterviewSolution

1.	The value of `3(sinx-cosx)^(4)+6(sinx+cosx)^(2)+4(sin^(6)xcos^(6)x)` isA. 14B. 11C. 12D. 13
Answer» Correct Answer - d `3(sinx-cosx)^(4)+6(sinx+cosx)^(2)+4(sin^(6)x+cos^(6)x)` Put `x=90^(@)` `3(sin90^(@)-cos90^(@))^(2)+6(sin90^(@))` `=3(1-0)^(4)+ 6(1+0) ^(2)+4(1^(6)+0)` `=3+ 6+4= 13`
