Answer» Let g(x)=ax+b, where `a lt 0` and g is defined from [1,3] onto [0,2] then the value of `cot(cos^(-1)(|sinx|+|cos x|)+sin^(-1)(-|cosx|-|sinx|))` is equal to (A) g (B) g(2) (C*)g(3) (D)g(1)+g(3) Consider `F(s)=cot(cos^(-1)(|sinx|+|cos x|)+sin^(-1)(-|cosx|-|sinx|))` But `|sinx|+|cosx| in [1,sqrt(2)]AA x in R` `:. F(x)=cot(cos^(-1)(1)+sin^(-1)(-1))=cot(0-(pi)/(2))=0=g(3)" " `(AsF(x)=0,`AAx in D_(F)`) |
