begin mathsize 16px style LHS equals tan squared straight theta minus sin squared straight theta equals fraction numerator sin squared space straight theta over denominator cos squared straight theta end fraction minus sin squared space straight theta equals fraction numerator sin squared space straight theta minus sin squared space θcos squared straight theta over denominator cos squared straight theta end fraction equals fraction numerator sin squared space straight theta left parenthesis 1 minus cos squared straight theta right parenthesis over denominator cos squared straight theta end fraction equals fraction numerator sin squared space straight theta cross times sin squared straight theta over denominator cos squared straight theta end fraction equals fraction numerator sin squared space straight theta over denominator cos squared straight theta end fraction cross times sin squared space straight theta equals tan squared straight theta cross times sin squared straight theta equals RHS end style
