We know that a “number squared” refers to the product of the number with itself. So, to find a square, we simply multiply the number with itself once.What is a cubed number? A“number cubed” refers to the multiplication of the number with itself and again by itself, i.e., ...
This equation says that energy is equal to the rest mass of the object times the speed of light squared (c is universally accepted as the speed of light). What is this equation actually telling us? Mathematically, since the speed of light is constant, an increase or decrease in the ...
R2shows how well terms (data points) fit a curve or line. Adjusted R2also indicates how well terms fit a curve or line, but adjusts for the number of terms in a model. If you add more and moreuselessvariablesto a model, adjusted r-squared will decrease. If you add moreusefulvariables...
Definition:R squared, also called coefficient of determination, is a statistical calculation that measures the degree of interrelation and dependence between two variables. In other words, it is a formula that determines how much a variable’s behavior can explain the behavior of another variable. ...

Hence tan A = 2 (.5 W / √(H2 + D2)), or simply tan A = 1 / √(H2 + D2), where “H” is the height of the observer. Because height is a constant, the denominator is changed by the square root of D squared, so we can further simplify the expression ...
