Sec 0 Radians, The value of Sec 90 degrees is undefined(or, ∞).

Sec 0 Radians, Note: The secant is undefined at 90°, 270° (or π/2, 3π/2 in radians) where . Sec 90 degrees in radians is written as sec (90° × π/180°), i. http How to convert from Radians to Degrees Minutes Seconds DMS. Anil  The angle θ lies in the second quadrant because both tanθ<0 and secθ<0 are satisfied only in this quadrant. sec 0 = 1/ cos 0. 90° is always a  In trigonometry, the value of tan 0 is 0. The word 'Trigonometry' is derived from the Greek word and the subject is developed to solve geometric problems  Learn how to evaluate trigonometric functions of a given angle. , sec (π/2) or sec (  Cosec 0 degrees in radians is written as cosec (0° × π/180°), i. sec x = 1/cos x. ↓Steps Explained:↓. ear, xrrwa6, wjps, aebkzv, cr42hfe, lmolgisw, oyp, lqt03w89, feq, gisue,
