Prove: (iii) "sec" (270^(@) - theta) "sec" (90^(@)- theta) - tan (270^@ - theta) tan (90^(@) + theta) = -1

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 : (cot(90^(@)-theta))/(tantheta)+("cosec"(90^(@)-theta)sintheta)/(tan(90^(@)-theta))=sec^(2)theta

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

(tan(90^@-theta) cot theta)/(cosec^2 theta)-cos^2 theta=0

If xsin(90^@-theta)cot(90^@-theta)=cos(90^@-theta) , then x=

tan theta+tan(90^(@)-theta)=sec theta xx sec(90^(@)-theta)
