if tan alpha = root 3 and tan beta = 1/ root 3 , find the value of sin (alpha + beta)
answer = 1
just substitute the values in right angle triangle and find sin alpha and sin beta
then apply it in formula,
sin(alpha+beta) = sin alpha. cos beta + cos alpha. sin beta
just substitute the values in right angle triangle and find sin alpha and sin beta
then apply it in formula,
sin(alpha+beta) = sin alpha. cos beta + cos alpha. sin beta
