Can the sine of an angle ever be 2
WebDec 15, 2024 · So it would make perfect sense to have a negative hypotenuse, but this would mean the angle is not where you expect it to be: a hypotenuse of − 2 means going 2 units in the opposite direction to that given by the angle. Here's what that might look like: sin 135 o = − 2 − 2 = 1 2. WebSep 15, 2024 · The Law of Cosines can also be used to solve triangles in Case 2 (two sides and one opposite angle), though it is less commonly used for that purpose than the Law of Sines. The following example gives an idea of how to do this. Example 2.2.5: Case 2 - Two sides and one opposite angle Known Solve the triangle ABC given a = 18, A = 25 …

WebAnswer: The height of the wall is 22√3 ft. Example 3: Find the value of sin 135° using sine identities. Solution: To find the value of sin 135°, we will use the angle sum property of sine given by, sin (a + b) = sin a cos b + sin b cos a and … WebJan 2, 2024 · ThePythagoreanIdentity is still true when we use the trigonometric functions of an angle. That is, for any angle, cos(θ)2 + sin(θ)2 = 1. In addition, we still have the inverse trigonometric functions. In particular, θ = arcsin(x) = sin − 1(x) means sin(θ) = x and − π 2 ≤ θ ≤ π 2 or − 90 ∘ ≤ θ ≤ 90 ∘.
WebSine of an angle cannot be 2,as you must be knowing, sin90=1,u may conclude that sin180=2.but 180 degree cannot be an angle of a triangle, Hope Can the sine of an … WebMar 28, 2024 · The value of sine of an angle can never be 2 let's understand it with the trigonometry concept.

WebFeb 14, 2024 · We want to see if in the interval [0, 2π) can the sine and cosine values of radian measures ever be equal. So we basically want to solve: sin (θ) = cos (θ) or: sin (θ)/cos (θ) = tan (θ) = 1 Now we can apply the inverse tangent function, Atan (x) to both sides, so we get: Atan (tan (θ)) = Atan (1) θ = 0.785 rad
