In a triangle tan A:tan B:tan C=1:2:3, then a^(2):b^(2):c^(2) equals

In /_ABC, if tan A:tan B:tan C=1:2:3, then sin A:sin B:sin C=?

In a delta ABC, if tan A:tan B:tan C=3:4:5 then the value of sin A:sin B:sin C is equal to

If A+B+C=pi, prove that (tan A)/(tan B tan C)+(tan B)/(tan Atan C)+(tan C)/(tan A tan B)=tan A+tan B+tan C-2cot A-2cot B-2cot C

In a ABC, if tan A:tan B:tan C=3:4:5 then the value of sin A sin B sin C is equal to (a) (2)/(sqrt(5)) (b) (2sqrt(5))/(7)(2sqrt(5))/(9) (d) (2)/(3sqrt(5))

If 0^circ < A < 90^circ and (sin x+cos x)/cos^3 x = atan^3 x+btan^2 x+ctan x+d ,then a+2b+3c+4d=

Prove that: tan7A-tan5A-tan2A=tan7Atan5Atan2A
