That means the radians to degrees formula is predictable: degrees = 180°/π × radians. Let's look at an example: What is a 300° angle in radians? radians = π/180° × 300° = ⁵⁄₃π rad., If you're preparing the big feast on Turkey Day this year, you'd better not screw it up. Whether you’ve happily volunteered for the position of “Thanksgiving preparer” or it was th..., Question: Find the reference angle, the quadrant of the terminal side, and the sine and cosine of 315º. Enter the exact answers. A) the The terminal side of the angle 315° lies in quadrant Click for List I II B) Its reference angle is Number IV III ab sin (a) 00 R LIU <.ysin (315") = ab sin (a) 8 R cos (315°) = 3 CH Dicas. There are 3 steps ..., For sin 315 degrees, the angle 315° lies between 270° and 360° (Fourth Quadrant ). Since sine function is negative in the fourth quadrant, thus sin 315° value = - (1/√2) or -0.7071067. . . ⇒ sin 315° = sin 675° = sin 1035°, and so on. Note: Since, sine is an odd function, the value of sin (-315°) = -sin (315°)., sin(135) sin ( 135) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. sin(45) sin ( 45) The exact value of sin(45) sin ( 45) is √2 2 2 2. √2 2 2 2. The result can be shown in multiple forms. Exact Form: √2 2 2 2. Decimal Form: 0.70710678… 0.70710678 …, sin(60 degrees), cos(2pi / 3), tan(11pi / 6), sin(-135 degrees) Evaluate 1 (need unit circle) Evaluate 2 (need paper) More evaluation. What angle(s) have ... sin(-135 degrees) What is -sqrt(2)/2. 400. sec(-240 degrees) What is -2. 400. 2pi / 3 and 5pi / 3 have the same value for these TWO trig functions., The sine of an angle is the length of the opposite side divided by the length of the hypotenuse with the assumption that the angle is acute (. 0 ° < α < 90 °. \small0\degree < \alpha < 90\degree 0° < α < 90° or. 0 < α < π / 2. \small0 < \alpha < \pi/2 0 < α < π/2 ). The other sine definition is based on the unit circle., Trigonometry. Trigonometry questions and answers. Without using a calculator, compute the sine and cosine of 135° by using the reference angle.What is the reference angle? degrees.In what quadrant is this angle? (answer 1, 2, 3, or 4)sin (135°)=cos (135°)= (Type sqrt (2) for 22 and sqrt (3) for 32.)Question Help:Video.
