In `Delta ABC`, circumrdius is 3 inradius is 1.5 units. The value of a `acot^(2)A+b^(2)cot^(3)B+c^(3)cot^(4)C` is

If circum-radius and in-radius of a triangle ABC be 10 and 3 units respectively , then a cot A +b cot B +c cot C is equal to

If circum-radius and in-radius of a triangle ABC be 10 and 3 units respectively , then a cot A + cot B + cot C is equal to

In a triangle ABC if b+c=3a then find the value of cot((B)/(2))cot((C)/(2))

In a triangle ABC if b+c=3a then find the value of cot(B/2)cot(C/2)

In a triangle ABC if b+c=3a then find the value of cot(B/2)cot(C/2)

In a triangle ABC if b+c=3a then find the value of cot(B/2)cot(C/2)

In Delta ABC, the value of ((cot A)/(2)(cot B)/(2)-1)/((cot A)/(2)(cot B)/(2)) is

In a Delta^(Ie)ABC, if sin A sin B sin C=(1)/(3) then the value of cot A cot B+cot B cot C+cot C cot A is
