[tan A=(3)/(4)quad " He "quad A+B],[(y)/(varepsilon)" cot "B]

If tan A=(3)/(4) and A+B=90o, then what is the value of cot B?

If tan A=(1)/(3 ) and tan B=(2)/(7) , then cot (A-B)=

If tan A=(1)/(3), tan B=(2)/(7) then cot (A+B)=

if tan(2a-3b)*tan(4b-a)=1a,b varepsilon(0,(pi)/(2)) then the value of tan((a+b)/(6))

(tan A + tan B)/( cot A + cot B)+(1- tan A tan B)/( 1- cot A cot B)=

If cot A =(4)/(3) and (A+B)=90^(@) , what is the value of tan B?

If A+B+C=180^(@) " then " sum(cot A + cot B)/(tan A + tan B)=

A relation R in a set A is called ... if (a,b)varepsilon R implies that (b,a)varepsilon R for all a,b varepsilon A

If A+B+C=pi, show that : tan.(A)/(2)tan.(B)/(2)+tan.(B)/(2)tan.(C)/(2)+tan.(C)/(2)tan.(A)/(2)=1 Hence deduce that : cot.(A)/(2)+cot.(B)/(2)+.cot.(C)/(2)=cot.(A)/(2).cot.(B)/(2)tan.(C)/(2) .
