which pythagorean identity is correct?A. sin2theta+1=cos2thetaB. tan2theta+1=sec2thetaC. 1-cot2theta=csc2thetaD. 1-cos2theta=tan2theta

Answer:The pythagorean identity that is correct is option B:B. tan^2(theta)+1=sec^2(theta)The pythagorean identities are:1.) sin^2(theta) + cos^2(theta) = 12.) tan^2(theta) + 1 = sec^2(theta)3.) 1 + cot^2(theta) = csc^2(theta)Then the pythagorean identity that is correct is option B:B. tan^2(theta)+1=sec^2(theta)
