`(sin(-theta)tan(90^@+theta)tan(180^@-theta))/(sin(180^@-theta)cos(90^@-theta)cos360^@-theta))=sec theta cosec theta`

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

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

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

Prove that (cos(90^(@)-theta))/(1+sin(90^(@)-theta))+(1+sin(90^(@)-theta))/(cos(90^(@)-theta))=2cosec theta

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

sin(90+theta)+cos(90-theta)+tan(180-theta)+cot(180+theta)

The value of (cos(90^(0)-theta)sec(90^(@)-theta)tan theta)/(csc(90^(@)-theta)sin(90^(@)-theta)cot(90^(@)-theta))+(tan(90^(@)-theta))/(cot theta) is 1(b)-1(c)2(d)-2

What is the value of (tan (90^@-theta) sec (180^@-theta)sin(-theta))/(sin (180^@+theta) cot (360^@-theta) "cosec"(90^@-theta)) ?

Simplify the following: (i) "sin"(90^(@)+theta)"tan"(270^(@)+theta)cot(90^(@)+theta) cosec(270^(@)+theta) (ii) ("sin"(-theta)"tan"(180^(@)+theta)"tan"(90^(@)+theta))/(cot(90^(@)-theta)cos(360^(@)-theta)"sin"(180^(@)-theta))
