if a +b=90 deg. find value of tan a and tan b
Assume
tan a + tan b = 90 take it as eqn. 1
tan a = 90-tan b take it as eqn.2
eqn 2 in 1
90-tanb+tanb=90
therefor
tana and tanb has eual value as 0
tan a + tan b = 90 take it as eqn. 1
tan a = 90-tan b take it as eqn.2
eqn 2 in 1
90-tanb+tanb=90
therefor
tana and tanb has eual value as 0
