Make the expression negative because sine is negative in the third 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., Trigonometry. Find the Exact Value sin (105) sin(105) sin ( 105) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. sin(75) sin ( 75) Split 75 75 into two angles where the values of the six trigonometric functions are known. sin(30+45) sin ( 30 + 45), a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 180°/π ~ 57.3 degrees. secant. the length of the hypotenuse divided by the length of the adjacent side. Also equals 1/cos (θ) sin. sin (θ) is the ratio of the opposite side of angle θ ...
