Definition of Sec and Tan = 1/Cos2A - Sin2A/Cos2A Combining Fractions = (1 - Sin2A) / (Cos2A) Apply Double Angle Formula = (1 - 2SinACosA How can I solve sinA-cosA=1 where 0 degree<=A<=90 degree. Thank you. Nazrul,. One way to approach this problem is to use sin2A = 1 - cos2A and hence write. Show that 1+sin2Acos2A=cosA+sinAcosA−sinA=cot(π4−A).
