Two triangles are said to be similar if their corresponding angles are of equal measure and their corresponding sides are in the same ratio. Also, if the angles are of the same measure, then by using the sine law, we can say that the corresponding sides will also be in the same ratio....
Test items assessed participants' ability to identify graphed reflections and vertical and horizontal shifts for cubic, square, logarithmic, exponential, andsine formulas. Figures 6 and 7 show 2 of the 36 test screens that assessed novel relations. ...
Sin inverse of x is the inverse of the sine function. i.e., if y = sin x then x = sin-1(y). Here, sin-1 is the inverse function of sine. How to Find the Inverse Sine of x? To find the inverse sine of any number, just see what angle of sine gives that number. For exam...

The double angle formula is used to calculate sin 2x, cos 2x, tan 2x, for any given angle 'x'. The sine double angle formula for an angle 'x' is sin 2x = 2sin(x)cos(x).What is the Double Angle Formula? The double angle formula can find the value of twice an angle under sine...
The idea of sine and cosine can be applied for every real number, and not only for the angles of a right triangle. The notion of a tangent, however, cannot be extended to some numbers because it is the ratio between the sine and the cosine. Because it is a fraction, the denominator ...
Sine is equal to the ratio of the length of the opposing side to the length of the hypotenuse side for any right-angled triangle measured with any of the angles. So, based on the graph, sinθ = y/1 = 1/1 As a result, the fractional value of sin 90 degrees is 1/ 1. 90° Sin...

How much light bends when passing from one medium into another is determined by Snell's law. For an angle of incidence _θi and angle of refraction θr_, \(n_i\sin{\theta_i}=n_r\sin{\theta_r}\) where _ni_ is the refractive index of the incident medium ...
