Simplify `(sin(180^@+theta)cos(360^@-theta)tan(270^@-theta))/(sec^2(90^@+theta)tan(-theta)sin(270^@+theta)`

Simplify (sin(270^@+theta)costheta+sin(270^@-theta)sintheta)/(sin(180^@-theta)costheta+sin(270^@-theta)cos(540^@+theta))

Simplify: (cos(90^@+theta)sec(-theta)tan(180^@-theta))/(sec(360^@+theta)sin(180^@+theta)cot(90^@-theta))

Simplify (cos(90^@+theta)sec (-theta)tan(180^(@)-theta))/(sec(360^(@)-theta)sin(180^(@)+theta)cot (90^(@)+theta))

(cos(90^@+theta)sec(-theta)tan(180^@-theta))/(sin(360^@+theta)sec(180^@+theta)cot(90^@-theta))=

sin(270^(@)-theta).sin(90^(@)-theta)-cos(270^(@)-theta).cos(90^(@)+theta)=

The value of (cos(90^@ - theta)sec(90^@ - theta) tan theta)/(cosec(90^@ - theta)sin(90^@ - theta)cot(90^@ - theta) (tan(90^@ - theta))/(cot theta) is____

Prove that: (sin(180^(@)+theta)cos(90^(@)+theta)tan(270^(@)-theta)cot(360^(@)-theta))/(sin(360^(@)-theta)cos(360^(@)+theta)cos ec(-theta)sin(270^(@)+theta))=1

Simplify the following : (sin (- theta) tan(180^@ +theta) tan (90^@ +theta))/(cot (90^@-theta)cos (360^@-theta) sin (180^@-theta)) .
