WebMar 17, 2024 · 5. Divide your sine values by the cosine values to fill the tangent row. Simply speaking, tangent = sine/cosine. Therefore, for every angle, take its sine value and divide … Webe^ (i*-i) = cos (-i) + i sin (-i). Recall that cosine and sine are even and odd functions, in this order. If we extend this concept to complex numbers and also use the fact that i^2=-1, we can rewrite the pair of equations as e^ (-1) = cos (i) + i sin (i) and e^ (1) = cos (i) - i sin (i). WebSine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is To calculate them: Divide the length of one side by another side … The sine function sin takes angle θ and gives the ratio opposite hypotenuse . ...
