if `sintheta-costheta=1/2` then the value of `1/(sintheta+costheta)`

If sintheta costheta=1/2 what is the value of (sintheta-costheta)^2 ?

If sintheta + cos theta =1 , then the value of sintheta - costheta is:

If costheta:sintheta=1:2 , then find the value of (8costheta-2sintheta)/(4costheta+2sintheta)

If sintheta - costheta = 1 , then prove that sintheta + costheta =+-1

If sintheta + 2 costheta=1 ,then prove that 2sintheta-costheta=2 .

If sintheta + 2 costheta=1 ,then prove that 2sintheta-costheta=2 .

If costheta-sintheta=sqrt(2)costheta , then find the value of costheta+sintheta .

If (1+ sintheta-costheta)/(1+ sintheta + costheta)+(1+sintheta+costheta)/(1+sintheta-costheta)= 4 , then which of the following values will be suitable for theta ?

If costheta+sintheta=sqrt(2)costheta ,then find the value of (costheta-sintheta)/(sintheta) .
