Solution. Evaluate the given degree value for all trigonometric angles. Let the given degree be θ = 270 °. So, the value of θ for all trigonometric angles is as follows, π 𝛑 π 𝛑 ⇒ sin 270 ° = sin ( 3 × π 2 + 0) [ π 2 = 90 °] sin 270 ° = - cos 0 ° sin 270 ° = - 1 [ c o s 0 ° = 1]
cos 270 ∘ = cos (180 ∘ + 90 ∘) 180 ∘ + θ is in third quadrant.By ASTC rule, cos θ is negative in third quadrant. Hence cos ( 180 ∘ + 60 ∘ ) = cos 90 ∘ = 0
The value of cos 270 degrees is 0. Cos 270 degrees in radians is written as cos (270° × π/180°), i.e., cos (3π/2) or cos (4.712388. . .). In this article, we will discuss the methods to find the value of cos 270 degrees with examples.
6 days ago · For cosine of 270 degrees: We can write ${{270}^{\circ }}\text{ as }\left( {{270}^{\circ }}+{{0}^{\circ }} \right)$ . Or, in equation form $\cos \left( {{270}^{\circ }} \right)=\cos \left( {{270}^{\circ }}+{{0}^{\circ }} \right)...\left( iii \right)$ We know the trigonometric identity $\cos \left( {{270}^{\circ }}+\theta \right)=\sin \theta $.
The cosine function (or cos function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it is itself the complement of sine(co+sine).
