if 1+sin theta+sin 2 theta+.....infinity=4+2root3 where 0 then theta=??? pls very urgent
When we see in LHSThis is a GP of infinite termsHenceSum of GP of infinite terms = 1/(1- sin)But 1/(1-sin) = 4 + 231- sin = (4 - 23)/(16-12)1- sin = (2 - 3) / 22 Sin = 3Sin = 3 /2As we knowSin = Sin 60Hence = 60 degree
