Sec A +tan A= p then find the value of cosec A

1.	Sec A +tan A= p then find the value of cosec A
Answer» 1/cosA + sinA/cosA = p1 + sinA = pcosAcosA = p root (1 - sin2A) (1 + sinA)2 = p2(1 - sin2A) D = 4 - 4 (1 + p2)(1 - p2) / 4 - 4(1 - p4) =4p4SinA = - 2 +_root(4p4)/ 2(1 + p2) - 1+_p2/1 + p2 p2-1/p2+1 = -1CosecA = p2-1/p2-1 = - 1
