Question

If tan Alpha = root 3 and tan Beta= 1 upon root 3 then value of
cot( alpha + beta) is what ?

Shan Singh · Accepted Answer

tan alpha = root3
alpha = 60
tan beta = 1/root3
beta = 30
cot(60+30) = cot 90 = 0

If tan Alpha = root 3 and tan Beta= 1 upon root 3 then value of cot( alpha + beta) is what ?
