If `=|1 3costheta1s intheta1 3costheta1s intheta1|` , then the value of `(_(m a x))//2`

If Delta = |[1, 3costheta, 1], [sintheta, 1, 3costheta], [1, sintheta, 1]|, the maximum value of Delta is

If sintheta+costheta=1 , then the value of sin2theta is

If (2sintheta-costheta)/(costheta+sintheta)=1 , then value of cottheta is :

If Sintheta + Costheta = 1 Sintheta - Costheta = ?

(1-costheta)/(1+costheta)+(1+costheta)/(1-costheta)=

costheta/(cosec theta+1)+costheta/(cosectheta-1)=2

If sintheta_(1)+sintheta_(2)+sintheta_(3)+sintheta_(4)=4 , then what is the value of costheta_(1)+costheta_(2)+costheta_(3)+costheta_(4)= ?

If |{:(x,sintheta,costheta),(-sintheta,-x,1),(costheta,1,x):}|=8 , then the value of x is :
