Solution. Find the value given trigonometric expression. Given, sin 270 ∘ can be expressed as, sin 270 ∘ = sin ( 180 ∘ + 90 ∘) Since sin is a periodic function of time period 2 π, also negative in third quadrant or sin. ( π + θ) = − sin. θ ,where π = 180 ∘. Therefore, sin 270 ∘ = sin ( 180 ∘ + 90 ∘) = - sin 90 ∘ = - 1 ∴ sin 270 ∘ = - 1.
The value of sin 270 degrees is -1. Sin 270 degrees in radians is written as sin (270° × π/180°), i.e., sin (3π/2) or sin (4.712388. . .). In this article, we will discuss the methods to find the value of sin 270 degrees with examples.
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.
Find the Exact Value sin (270 degrees ) Step 1. 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. Step 2. The exact value of is . Step 3. Multiply by .
Sine Function Definition. In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function is used to find the unknown angle or sides of a right triangle.
