Number of solutions of the equation `sec^(-1)((2)/((1)/(x)+x))+picospix=0` |
|
Answer» Correct Answer - 1 `sec^(-1)((2)/((1)/(x)+x))=sec^(-1)((2x)/(1+x^(2)))` `because` domain of `sec^(-1)((2)/((1)/(x)+x))` is `x=1,-1` `x=1` does not satisfy if `x=-1` then `sec^(-1)((2)/((1)/(x)+x))+picosx` `=sec^(-1)(-1)+picos(-pi)=pi-pi=0` |
