If in a triangle `A B C` angle `B=90^0` then `tan^2(A/2)` is `(b-c)/a` (b) `(b-c)/(b+c)` (c) `(b+c)/(b-c)` (d) `(b+c)/a`

If A, B, C are the angles of a triangle then tan ((B+C)/2)=

In a triangle A B C , , if C is a right angle, then tan^(-1)(a/(b+c))+tan^(-1)(b/(c+a))= (a) pi/3 (b) pi/4 (c) (5pi)/2 (d) pi/6

In a triangle A B C , if a, b, c are in A.P then tan (A)/(2), tan (B)/(2), tan (C)/(2) are in

If an a triangle A B C , b=3 c, a n d C-B=90^0, then find the value of tanB

If an a triangle A B C , b=3 c, a n d C-B=90^0, then find the value of tanB

If sides of triangle ABC are a,b and c such that 2b=a+c then (b)/(c)>(2)/(3)( b) (b)/(c)>(1)/(3)(b)/(c)<2 (d) (b)/(c)<(3)/(2)

In a triangle A B C prove that a/(a+c)+b/(c+a)+c/(a+b)<2

In triangle ABC, prove that 'tan((B-C)/2)=(b-c)/(b+c)cotA/2 tan(C-A)/2=(c-a)/(c+a)cotB/2 tan(A-B)/2=(a-b)/(a+b)cotC/2

In a triangle A B C , right angled at C ,t a n A+t a n B is equal to a. a+b b. (c^2)/(a b) c. (a^2)/(b c) d. (b^2)/(a c)

In Delta ABC, if /_C=90^(@), then prove that tan((A)/(2))=sqrt((c-b)/(c+b))=(a)/(b+c)
