Cosine is adjacent over hypotenuse Tangent is opposite over adjacent These trigonometric ratios are used for right triangles to determine theta, or the non-right angles in the triangle. If theta is known then they can also be used to determine the length of a triangle side. These right ...
Relationship to cosine More Articles / Correlation Coefficients What is a correlation coefficient? A correlation coefficient is a measure of the strength of a linear relationship between two variables. In general, correlation coefficient values range from -1 to 1: 1 = a strong positive linear relati...
