Sin 270 degrees is the value of sine trigonometric function for an angle equal to 270 degrees. Understand methods to find the value of sin 270 degrees with examples and FAQs.

Use our sin (x) calculator to find the exact value of sine of 270 degrees - sin (270 °) - or the sine of any angle in degrees and in radians.

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because sine is negative in the third quadrant. The exact value of sin(90) sin (90) is 1 1. Multiply −1 - 1 by 1 1.

Answer: Sin 270 degrees has a value of -1. In radians, sin 270 degrees is represented as sin (270°/180°), i.e., sin (3/2 (π)) means sin (4.712388. . .). Sin (-270 degrees): 1 Sin 270 degrees in radians: sin (3/2) = sin (4.7123889 . . .) The angle 270° is already on the negatives y-axis with sin 270 degrees. Therefore, sin 270° values = -1

Calculate the value of the sin of 245 ° To enter an angle in radians, enter sin (245RAD) sin (245 °) = -0.90630778703665 Sine, in mathematics, is a trigonometric function of an angle.

2024年3月15日 · The sine of 270 degrees is -1. The sine function gives us the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle.

Complete step by step solution: According to the given question, we need to evaluate sin 270. If in a right angled triangle θ represents one of its acute angle then by definition we can write sin θ = O p p o s i t e H y p o t e n u s e We know that sin 270 can be expressed as s i n 270 = s i n (3 × 90 + 0 ) Also, we know that

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because sine is negative in the third quadrant. The exact value of sin(90) sin (90) is 1 1. Multiply −1 - 1 by 1 1.
