WebNov 23, 2024 · The negative angle identities give the relationship between trigonometric functions when we take the trigonometric function of a negative angle. These negative angle identities are as follows. WebNegative Angle Identities Identities also exist to relate the value of a trigonometric function at a given angle to the value of that function at the opposite of the given angle. Here are these identities: sin (- ≈íø) = - sin (≈íø) cos (- ≈íø) = cos (≈íø) tan (- ≈íø) = - tan (≈íø) csc (- ≈íø) = - csc (≈íø) sec (- ≈íø) = sec (≈íø)

WebThe hypotenuse will be the larger value (√2) and the other two sides will both be 1. This makes sense, especially when we plug these values into the Pythagorean theorem: a^2 + b^2 = c^2 1^2 + 1^2 = (√2)^2 1 + 1 = 2 2 = 2 So now we have our sides, so we can very easily find sin/cos/tan values. sin = O/H = 1/√2 cos = A/H = 1/√2 tan = O/A = 1/1 = 1 WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0. So tan (90) is undefined. ( 7 votes) Show more...

WebDec 20, 2024 · We can interpret the tangent of a negative angle as tan( − θ) = sin( − θ) cos( − θ) = − sinθ cosθ = − tanθ. Tangent is therefore an odd function. The cotangent identity, cot( − θ) = − cotθ, also follows from the sine and cosine identities. We can interpret the cotangent of a negative angle as cot( − θ) = cos( − θ) sin( − θ) = cosθ − sinθ = − cotθ. Web(iii) In the IVth quadrant, the sign of "tan" is negative.
