Applyingtrigonometric identities, sinsin 180° – B = sinsin B . Thus, if we are to compute the value in terms ofh, the equation will be: h = b sinsin A and h = a sinsin B . Thus, we can now say that b sinsin A = a sinsin B . Moreover, if we putaandbto the left ...
A new study published in the journal Historia Mathematica finds that a small clay tablet called Plimpton 322 might actually be a trigonometric table — a tool that allows you to use a single known ratio of the sides of a right-angle triangle to figure out the other two ratios. Based on ...
It is calculated by the ratio of the circumference of a circle to its diameter. circumference = diameter * π or circumference = 2 * π * radius, this means that the diameter = 2 x radius. When is the DEGREES function useful? The trigonometric arc functions return a value in radians. ...
FAQ: How to get from tan(a)/tan(b) to sin(a)/sin(b) or something simmilar How do I convert tan(a)/tan(b) to sin(a)/sin(b) or something similar? To convert from tan(a)/tan(b) to sin(a)/sin(b), you can use the trigonometric identity: tan(x) = sin...
