Comprehension We are familiar with elementary conditional identities in a triangle. We know that A+B+C=180( in a triangle. General conditional identities can be derived by taking sine, cosine or tangent of both sides or taking sine, cosines, or tangents after transposing one angle to the other sied. We may also divide by 2 and follow the same steps. In any triangle sin3(= sin(A-() sin (B-() sin(C-() then, cot( must be equal to
cotA cotB cotC
cotA + cotB + cotC
tan A + tan B + tan C
