## Arctangent definition

The arctangent function is the inverse function of y = tan(x).

arctan(y) = tan-1(y) = x+

For every

k = {...,-2,-1,0,1,2,...}

For example, If the tangent of 45° is 1:

tan(45°) = 1

Then the arctangent of 1 is 45°:

arctan(1) = tan-1(1) = 45°

Proportionate Equations and Corollary Equations - There are changes of conditions that enable one to go from the condition to be tackled to the alleged identical conditions and outcome conditions, by the arrangements of which it is conceivable to decide the arrangement of the first condition. In this article, we will break down in detail which conditions are called proportionate and which conditions are outcomes, give the fitting definitions, give illustrative models and disclose how to discover the foundations of the condition from the known underlying foundations of the comparable condition and condition result.
