`lim_(e-gt0)(sqrt(1-costheta))/theta`

What is lim_(thetato0)(sqrt(1-costheta))/(theta) equal to?

If lim_(theta->0)((a(1-costheta))/(theta^2)-(bsintheta)/(theta))=1 then the value of 2b-a is -lambda , then the value of lambda is (1) 2 (2) 4 (3) 6 (4) 8

Evaluate the following : lim_(theta to 0)(1-costheta)/(2theta^(2))

Evaluate : lim_(thetararr0)[(1-costheta)/(theta^2)] .

Choose the correct option for the following lim_(thetararr0)sqrt[(1-cos9theta)/(1-cos16theta)] is :

lim_(theta rarr 0) (1-cos theta)/(theta. costheta)=

If pi le theta le (3pi)/2 , then sqrt((1+cos theta)/(1-costheta))+sqrt((1-costheta)/(1+costheta)) is equal to :

If alpha and beta are roots of x^(2)-(sqrt(1-cos 2 theta))x+theta=0 , where 0 lt theta lt (pi)/2 . Then lim_(theta to 0^(+))(1/(alpha)+1/(beta)) is
