WebExplanation: For sin 240 degrees, the angle 240° lies between 180° and 270° (Third Quadrant ). Since sine function is negative in the third quadrant, thus sin 240° value = - (√3/2) or -0.8660254. . . Since the sine function is a periodic function, we can represent sin 240° as, sin 240 degrees = sin (240° + n × 360°), n ∈ Z. Webb) cos 135° The corresponding acute angle is 45°. In the second quadrant, cos θ is negative. Therefore, cos 135° = −cos 45° = −½. c) tan 240° The corresponding acute angle is 60°. In the third quadrant, tan θ is positive. Therefore, tan 240° = tan 60° = . d) csc (−30)° The corresponding acute angle is 30°. hc svnt dracones sound and silence pdf
