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

Prove that: (sin(180^0+theta)cos(90^0+theta)t a n(270^0-theta)cot(360^0-theta))/(sin(360^0-theta)cos(360^0+theta)cos e c(-theta)"sin"(270^0+theta))=1

(cos(90^(@)-theta).sec(90^(@)-theta).tantheta)/(cosec(90^(@)-theta).sin(90^(@)-theta).cot(90^(@)-theta))=?

Let (sin(180^(@)+theta)cos(270^(@)-theta)cot(theta-360^(@)))/(cos(theta-90^(@))sin(360^(@)-theta)tan(270^(@)+theta))=sqrt(a)(sin^(90^(@)-theta)+sin^(2)(90^(@)+theta)-1)/(1-cos^(2)(270^(@)-theta)-cos^(2)(270^(@)+theta))=b^(2) then determine the value of a+b, if (a+b) is a prime number

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

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

(sin(90^(@)-theta)sec(180^(@)-theta)sin(-theta))/(sin(180^(@)+theta)cot(360^(@)-theta)"cosec"(90^(@)+theta)) .

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