" 1."cos theta*tan theta=sin theta

Show that (1)/( cos theta ) -cos theta =tan theta .sin theta

Show that (1)/( cos theta ) -cos theta =tan theta .sin theta

Show that (1)/(cos theta) - cos theta = tan theta. sin theta

Show that (1)/( cos theta ) -cos theta =tan theta .sin theta

Show that (1)/( cos theta ) -cos theta =tan theta .sin theta

Show that (1)/( cos theta ) -cos theta =tan theta .sin theta

(sin theta+sin2 theta)/(1+cos theta+cos2 theta)=tan theta=sin theta*sec 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)

Consider the trigonometric expression sin(2A)/(1-cos 2A) amd sin(2A)/(1+cos 2A) .(iii)Prove that (1-cos theta)/sin theta=tan (theta/2)=(sin theta)/(1+cos theta) .

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