" साबित करें कि "tan^(-1)x+cot^(-1)x=(pi)/(2)

3tan^(-1)x+cot^(-1)x=pi

tan^(-1) x +cot^(-1)x =(pi)/(2) holds, when

Find x, if tan^(-1)4+cot^(-1)x=(pi)/(2) .

prove that tan^(-1)x+cot^(-1)x=pi/2

If tan^(-1)4+cot^(-1)x=(pi)/(2), then value of x is

If (tan^(-1)x)^(2) +(cot^(-1)x)^(2) =(5pi^(2))/(8) , then find x.

tan^(-1)(cot x)-tan^(-1)(cot2x)=

The solution set of inequality (tan^(-1)x)(cot^(-1)x)-(tan^(-1)x)(1+(pi)/(2))-2cot^(-1)x+2(1+(pi)/(2))gtlim_(yrarr-oo)[sec^(-1)y-(pi)/(2)] is (where [ . ]denotes the G.I.F.)
