निम्नलिखित को सिद्ध कीजिये- `(cos(90^(@)theta)sin(90^(@)theta))/(tan(90^(@)-theta))=sin^2theta`

sin(90^(@)-theta)costheta+cos(90^(@)-theta)sintheta= ………… .

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

sin theta cos(90^(@)-theta)+cos theta sin(90^(@)-theta)

(sin(90^(@) -theta)sin theta)/(tan theta) + sin^(2) theta is equal to

Simplify : (cos(-theta))/(sin (90^(@)+theta))

Prove that : (sin \theta . sin(90^(@) - \theta))/(cot (90^(@) - \theta)) = 1 - sin^(2) \theta

(sin(90^(@)-theta)sintheta)/tantheta + (cos(90^(@)-theta)costheta)/cottheta= ………… .

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

Find 'x' from the equation: "cosec"(90^(@)-theta)-x "sin"(90^(@)-theta)"tan"(180^(@)+theta)="sin"(90^(@)+theta) .
