WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
WebExplanation: For sin 180 degrees, the angle 180° lies on the negative x-axis. Thus, sin 180° value = 0. Since the sine function is a periodic function, we can represent sin 180° as, sin 180 degrees = sin (180° + n × 360°), n ∈ Z. ⇒ sin 180° = sin 540° = sin 900°, and so on. Note: Since, sine is an odd function, the value of sin ... WebWhat are the relations among all the trigonometrical ratios of (180° - θ)?
