ABC if median from B and C are perpendicular then the value of cot B + cot C can be 1 () 2 2 3 2 O 3

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 o+ABC, if cot A+cot B+cot C=0 then find the value of cos A cos B cos C

If in ABC,AC is double of AB ,then the value of cot((A)/(2))cot((B-C)/(2)) is equal to (1)/(3)(b)-(1)/(3)(c)3(d)(1)/(2)

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

If three sides a,b,c of a triangle ABC are in arithmetic progression, then the value of cot, A/2, cot, C/2 is (A) 1 (B) 2 (C) 3 (D) None of these

The value of cos^(2)17o-sin^(2)73o is (a) 1 (b) (1)/(3) (c) 0(d)-1
