3 days ago · The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse ), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse.
5 days ago · What is the value of Cos 180 degrees? We know that the exact value of cos 0 degrees is 1. So, cos 180 degrees which can be written as −(cos 0) is equal to −(1).

- Sin 180 degrees = 0.Cos 180 degrees = −1.Tan 180 degrees = 0.Sec 180 degrees = −1.Cot 180 degrees = Undefined
- We know that the exact value of cos 0 degrees is 1. So, cos 180 degrees which can be written as −(cos 0) is equal to −(1). Therefore, the value of...
- We can write, sin 180 as;Sin 180 = Sin (90+90)Since, sin (90+a) = cos aSo, sin (90+90) = cos 90As we know cos 90 = 0, Therefore, Sin 180 = 0.
3 days ago · The small-angle approximation is the term for the following estimates of the basic trigonometric functions, valid when \theta \approx 0: θ ≈ 0: \sin \theta \approx \theta, \qquad \cos \theta \approx 1 - \frac {\theta^2} {2} \approx 1, \qquad \tan \theta \approx \theta. sinθ ≈ θ, cosθ ≈ 1− 2θ2 ≈ 1, tanθ ≈ θ.
3 days ago · We find the relation between three angles and convert all trigonometric forms to their simplest form by substituting the value of \[\cot \theta \]. * The property \[\sin \left( {180 - \theta } \right) = \sin \theta \] * Here we use the property to group together \[\cos x\sin y + \sin x\cos y = \sin \left( {x + y} \right)\].
