Rate Problem-Lecture-17
Ratio variation-Lecture-16
Ratio, Proportion and Rate-Lecture-15
A rate is a ratio that compares two different kinds of numbers, such as miles per hour or dollars per pound. A unit rate compares a quantity to its unit of measure. Ratio Proportion and Rate
Percentage- Lecture-13
a percentage is a number or ratio that represents a fraction of 100. It is often denoted by the symbol “%” . Also When we say “Percent” we are really saying “per 100”. One percent (1%) means 1 per 100. Hence Use the percentage formula: P% * X = Y. Percentage
Graph in XY plane-Lecture-10
Coordinate system is a pair of perpendicular coordinate lines. Lines are called coordinate axes. Also the point where both interest is origin. Therefore point (x,y) is location on XY-plane. Graph in XY-Plane
Linear functions-Lecture 12
Two variable linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. Linear functions
Graphic linear system-Lecture-11
Linear system can be solve by graphing. A linear system that has exactly one solution. Hence it intersect at x- axis once. Graphing linear system
Differentiation
Differentiation is the action of computing a derivative. The derivative of a function y = f(x) of a variable x is a measure of the rate at which the value y of the function changes with respect to the change of the variable x. Differentiation
Differentiability
Differentiable functions of one variable is a function whose derivative exists at each point in its domain. Also function is differentiable at a point if it has a derivative there. Therefore function also continuous in given domain. Differentiable_function
