What is sin 120 degrees? Trigonometry Right Triangles Trigonometric Functions of Any Angle.Explanation: For sin 90 degrees, the angle 90° lies on the positive y-axis. Thus, sin 90° value = 1. Since the sine function is a periodic function, we can represent sin 90° as, sin 90 degrees = sin (90° + n × 360°), n ∈ Z. ⇒ sin 90° = sin 450° = sin 810°, and so on. Note: Since, sine is an odd function, the value of sin (-90 ...Jun 4, 2020 ... This video will show how to find the exact values of sin(30), sin(60), cos(30), cos(60) using special right triangle.Learn about the relationship between the sine & cosine of complementary angles, which are angles who together sum up to 90°. We want to prove that the sine of an angle equals the cosine of its complement. sin. ⁡. ( θ) = cos. ⁡. ( 90 ∘ − …Sine, is a trigonometric function of an angle. The sine of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to (which divided by) the length of the longest side of the triangle (thatis called the hypotenuse). What is vaue of Sine 0°? = 0sin-60°. = cos (90° + 60°) = cos 150°. = sin (180° + 60°) = sin 240°. -sin-60°. = cos (90° – 60°) = cos 30°. = sin (180° – 60°) = sin 120°. Note that sin-60° is periodic: sin (-60° + n …Hence, we get the values for sine ratios,i.e., 0, ½, 1/√2, √3/2, and 1 for angles 0°, 30°, 45°, 60° and 90° Now, write the values of sine degrees in reverse order to get the values of cosine for the same angles.
