Question 880630
{{{(1+tan^2(theta))/(csc^2(theta)) = tan^2(theta)}}}



{{{(sec^2(theta))/(csc^2(theta)) = tan^2(theta)}}}



{{{(1/cos^2(theta))/(1/sin^2(theta)) = tan^2(theta)}}}



{{{(1/cos^2(theta))*(sin^2(theta)/1) = tan^2(theta)}}}



{{{(sin^2(theta))/(cos^2(theta)) = tan^2(theta)}}}



{{{tan^2(theta) = tan^2(theta)}}} The identity is verified
