[" 4.Value of "cot[tan^(-1)alpha+cot^(-1)alpha]" is: "],[" (a) "1],[" (c) "0]

If tan alpha+cot alpha=a, then the value of tan^(4)alpha+cot^(4)alpha is equal to

If tan alpha+cot alpha=2 then

If alpha in (-(3pi)/2,-pi) , then the value of tan^(-1)(cot alpha)-cot^(-1)(tan alpha)+sin^(-1)(sin alpha)+cos^(-1)(cos alpha) is equal to

If alpha in(-(3 pi)/(2),-pi), then the value of tan^(-1)(cot alpha)-cot^(-1)(tan alpha)+sin^(-1)(sin alpha)+cos^(-1)(cot alpha) is equal to (a)2 pi+alpha(b)pi+alpha(c)0(d)pi-alpha

If tan alpha+cot alpha=m then value of tan^(4)alpha+cot^(4)alpha is

If tan alpha + cot alpha=a , then the value of tan^(4)alpha + cot^(4)alpha is equal to

If tan alpha + cot alpha=a , then the value of tan^(4)alpha + cot^(4)alpha is equal to

If cot^3alpha +cot ^2 alpha + cot alpha =1 then

If alpha in (-(pi)/(2), 0) , then find the value of tan^(-1) (cot alpha) - cot^(-1) (tan alpha)
