In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical ..., Free trigonometry calculator - calculate trignometric equations, prove identities and evaluate functions step-by-step, The hypothenuse AC can easily be calculated now: AC = √BC2 +AB2 = √12 +12 = √2. The sine is defined as the ratio between the opposed side and the hypothenuse. Therefore, sin45o = 1 √2 = √2 2. In decimal form, it is roughly 0.7071067812. Answer link. sin45^@=sqrt (2)/2 This is a common value, in which sin45^@=1/sqrt2., To find the value of cos 135 degrees using the unit circle: Rotate ‘r’ anticlockwise to form 135° angle with the positive x-axis. The cos of 135 degrees equals the x-coordinate (-0.7071) of the point of intersection (-0.7071, 0.7071) of unit circle and r. Hence the value of cos 135° = x = -0.7071 (approx), : Get the latest SIN CARS INDUSTRY AD Registered Shs stock price and detailed information including news, historical charts and realtime prices.

Stay informed. Last Updated: April ..., Solution. Calculate the value of sin 150 °: First, determine the sign of sin 150 °. It is clear that 150 ° belongs to the second quadrant. It is known that the values of sines are positive + in the second quadrant. It is also known that, sin ( 180 - x) ° = sin x °. Thus, sin 150 ° = sin 180 - 30 ° = sin 30 ° = 1 2.
