(15.)/(sec^(2)theta)=cot theta

Prove: ((1+cot^(2)theta)tan theta)/(sec^(2)theta)=cot theta

Prove: ((1+cot^2theta)tantheta)/(sec^2theta)=cottheta

Prove that: {1+cot theta-sec((pi)/(2)+theta)}{1+cot theta+sec((pi)/(2)+theta)}=2cot theta

Prove that (i) (1)/(("cosec" theta- cot theta ))=("cosec" theta + cot theta) (ii) ((sec theta - tan theta))/((sec theta + tan theta))=(1+ 2tan^(2) theta - 2 sec theta tan theta)

Find the value of (sec^(2)theta-1).cot^(2)theta

Prove that (tan theta+cot theta+1)(tan theta+cot theta-1)=sec^2 theta+cot^2 theta

Prove that (1+ cot theta + tan theta ) ( sin theta - cos theta) = (sec theta )/(cosec^(2) theta) - (cosec theta)/(sec^(2)theta) .

(Prove that )/(cp sec theta+1)+(cos ec theta+1)/(cot theta)=2sec theta
