O 0.5/1 points | Previous Answers SAlgTrig4 7.1.039 Verify the identity. tan(0) + cot(0) = sec(0) cse@) Use a Reciprocal Identity to rewrite the expression in terms of sir sin() cos(e) | cos( ) | v tan(0) + cot@) = + ,Explanation / Answer
1) cos^2 v / sin v = csc v - sin v
rewriting the given terms in sine only
cos^2 v / sin v = ( 1 - sin^2 v ) / sin v
= 1/ sin v - sin v
= csc v - sin v
which is right side
proved
2) tan theta + cot theta = sec theta csc theta
tan theta + cot theta = sin theta / cos theta + cos theta / sin theta
= 1 / cos theta sin theta
pythogorean identity is
( sin^2 theta + cos^2 theta ) / cos theta sin theta
= sec theta csc theta
which is right side
proved !
