How to solve sin feta
WebMay 2, 2016 · Explanation: sin(4θ) = cos(2θ) or 2sin(2θ)cos(2θ) −cos(2θ) = 0. or cos(2θ){2sin(2θ) −1} = 0. i.e. either cos(2θ) = 0 or 2sin(2θ) −1 = 0. If cos(2θ) = 0, 2θ = (2n +1)π 2 or θ = (2n +1) π 4. and if 2sin(2θ) −1 = 0, we have sin(2θ) = 1 2. and 2θ = nπ+ ( − 1)n π 6 or θ = n π 2 + ( −1)n π 12. Webcos (θ²) + sin (θ²), then that is NOT equal to 1, except for a few special angles such as θ=√ (2π), θ=0 or θ= ½√ (2π) If you mean: (cos θ )² + (sin θ)² = 1. Which is usually written as: …

WebJun 1, 2015 · The trig unit circle gives another arc x that has the same sin value (0.75): x = 180 - 48.59 = 131.41 deg Within the interval (0, 2pi), there are 2 answers: 48.59 and 131.41 WebSep 18, 2016 · To find the value of θ, we use the arcsine function, which is essentially the opposite of the sine function: arcsin(sinθ) = arcsin(b c) → θ = arcsin(b c) You may also see the arcsine function written as sin−1θ. It is important to understand the relationship between sine and arcsine.
Websin θ = y 1. Start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. sin θ = y 1 = 1 1. Therefore, sin 90 degree equals to the fractional value of 1/ 1.
