Proof of formula of Cot(A+B) and Cot(A-B)

Proof of Cot(A–B)=(CotA.CotB+1)/(CotB–CotA).

Cot(A+B)=(cotAcotB -1)/(cotB +cotA), cot(A-B) =(cotAcotB +1)/(cotB-cotA)

tan and cot formula of compound angles

Prove that:- cot(A+B+C)=(cotAcotBcotC-cotA-cotB-cotC)/(cotAcotB+cotBcotC+cotAcotC-1)

If A + B = 45 Prove that (cotA - 1)(cotB - 1) = 2

If Cot B = 12/5 , Prove that Tan sq B - Sin sq B = Sin ^4 B Sec ^2 B

(cotA + tanB)/(cotB + tanA) = cotAtanB Trigonometric Identity

Prove that : (cos A + cos B)/(cos A- cos B) = -cot ((A+B)/2)cot((A-B)/2)

cos(a + B) / (sin(a) * cos(B)) = cot(a) - tan(B)

「TanA + TanB = pかつCotA + CotB = qならばCot(A+B) =」
