What is the domain of validity for csctheta =start fraction 1 over sine theta end fraction? (1 point) all real numbers all real numbers except odd multiples of the fraction states pi over 2. all real numbers except even multiples of the fraction states pi over 2. all real numbers except multiples of pi 2. which identity is not used in the proof of the identity 1 + cot2theta = csc2theta? 1 + cot2theta = csc2theta 1 +cos squared theta over sin squared theta= csc2theta sin squared theta over sin squared theta+cos squared theta over sin squared theta= csc2theta sin squared theta plus cos squared theta over sin squared theta= csc2theta one over sin squared theta=csc2theta csc2theta = csc2theta (1 point) cotangent identity pythagorean identity reciprocal identity tangent identity?
