For sin 270 degrees, the angle 270° lies on the negative y-axis. Thus, sin 270° value = -1. Since the sine function is a periodic function, we can represent sin 270° as, sin 270 degrees = sin (270° + n × 360°), n ∈ Z. ⇒ sin 270° = sin 630° = sin 990°, and so on. Note: Since, sine is an odd function, the value of sin (-270°) = -sin ...
Find the Exact Value sin(120 degrees ) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Step 2. The exact ...
It uses functions such as sine, cosine, and tangent to describe the ratios of the sides of a right triangle based on its angles. What are the 3 types of trigonometry functions? The three basic trigonometric functions are: Sine (sin), Cosine (cos), and Tangent (tan).
Jan 18, 2016 · csc(120o) = 2 √3. sec(120o) = − 2. cot(120o) = − 1 √3. Answer link. Assuming that the angle is in degrees. sin (120^o) = sqrt (3)/2 cos (120^o) = -1/2 tan (120^o) = -sqrt3 csc (120^o) = 2/sqrt (3) sec (120^o) = -2 cot (120^o) = -1/sqrt (3)
The sine formula is: sin (α) = opposite hypotenuse = a c. Thus, the sine of angle α in a right triangle is equal to the opposite side’s length divided by the hypotenuse. To find the ratio of sine, simply enter the length of the opposite and hypotenuse and simplify. For example, let’s calculate the sine of angle α in a triangle with the ...
