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 ∘
Oct 23, 2015 · Find sin 270^@ On the trig unit circle, sin (270) = sin (90 + 180) = - sin 90 = - 1
Oct 12, 2017 · sin(270^o) = -1, cos (270^0) = 0, tan (270^0)= undefined. Consider the unit circle (a circle with radius 1). On the unit circle as graphed on an xy coordinate plane, with 0 degrees starting at (x,y) = (1,0): graph{x^2+y^2=1 [-1, 1, -1, 1]} If we draw a line from the origin at the angle we seek, then where that line intersects the unit circle, the sin of the angle will be equal to the y-coordinate, and the cosine will be equal to the x-coordinate, with the tangent being equal to the sine ...

In trigonometry formulas, we will learn all the basic formulas based on trigonometry ratios (sin,cos, tan) and identities as per Class 10, 11 and 12 syllabi. Also, find the downloadable PDF of trigonometric formulas at BYJU'S.
In the same way, we can find the trigonometric ratio values for angles beyond 90 degrees, such as 180°, 270° and 360°. Unit Circle. The concept of unit circle helps us to measure the angles of cos, sin and tan directly since the centre of the circle is located at the origin and radius is 1. Consider theta be an angle then,
1/sin x = cosec x; 1/cos x = sec x; 1/tan x = cot x; Steps to Create a Trigonometry Table Step 1: Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot. Step 2: Determine the value of sin
The value of sin 180 (sin pi) can be interpreted in terms of different angles like 0°, 90° and 270°. Assume that the unit circle in the Cartesian plane is subdivided into four quadrants. And we know that the value of sin 180 degrees in the Cartesian plane takes place in the second quadrant.
Example: Find the value of Sin 270°+2Tan 45 0. Solution: Sin 270°= -1. And Tan 45 0 =1. Therefore, Sin 270°+2Tan 45 0 = -1+2*1 = -1+2 = 1. Learn more about trigonometric functions and download BYJU’S-The Learning App for a better experience.
