" (x) "(sin theta+tan theta)/(cos theta)=tan theta(1+sec theta)

Prove: (sin theta + tan theta)/(cos theta) = tan theta (1 + sec theta)

(sin theta tan theta)/(1-cos theta)=1+sec theta

(sec theta+tan theta)/(sec theta-tan theta)+(sec theta-tan theta)/(sec theta+tan theta)

Prove that (sec theta-tan theta+1)/(sec theta+tan theta+1)=(1-sin theta)/(costheta) .

(cos theta)/(sec theta-tan theta)=1+sin theta

Prove that sin theta(1+tan theta)+cos theta(1+cot theta)=sec theta+cos ec theta

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

Prove: (tan theta)/(sec theta-1)=(tan theta+sec theta+1)/(tan theta+sec theta-1)

prove that (sec theta-tan theta-1)/(sec theta+tan theta-1)=tan theta-sec theta
