However, if only two sides of a triangle are given, finding the angles of a right triangle requires applying some basic trigonometric functions: for α: sin(α) = a / c so α = arcsin(a / c) (inverse sine); cos(α) = b / c so α = arccos(b / c) (inverse cosine); tan(α...
sin t=yThe definition of the cosine of angle t iscos t=((adjacent side))((hypotenuse))The adjacent side of the triangle formed in the unit circle is the distance from a point on the circumference of the circle to the y-axis, which is distance x. As usual, the hypotenuse is 1. ...
