WebUsing the above proved results we will prove all six trigonometrical ratios of (180° - θ). sin (270° + θ) = sin [1800 + 90° + θ] = sin [1800 + (90° + θ)] = - sin (90° + θ), [since sin (180° + θ) = - sin θ] Therefore, sin (270° + θ) = - cos θ, [since sin (90° + θ) = cos θ] cos (270° + θ) = cos [1800 + 90° + θ] = cos [I 800 + (90° + θ)] WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
Value of csc(270) or Cosec(270) - Cosecant - Web Conversion Online
WebJul 7, 2024 · As the cosecant function is the reciprocal of the sine function, 1 / sin 270° = csc270°. What is the value of Cosec 180 degree? Therefore, the value of cos 180° is -1.

WebOct 12, 2024 · 270° does not lies in 1st and 2nd Quadrant. Therefore cosec (360° – θ) = – cosec θ. cosec (270°) = cosec (360° – 90°) cosec (270°) = – cosec (90°) cosec (270°) … small sound bars for tv bose
Find the Exact Value csc(270 degrees ) Mathway
WebFor cosec 210 degrees, the angle 210° lies between 180° and 270° (Third Quadrant ). Since cosecant function is negative in the third quadrant, thus cosec 210° value = -2 Since the cosecant function is a periodic function, we can represent cosec 210° as, cosec 210 degrees = cosec (210° + n × 360°), n ∈ Z.
