## trigonometric formulas for Class 10

Trigonometry is quite a important chapter in Class 10 maths and lot of good questions comes in board examination also. Here is the trigonometric formulas for Class 10 in one page In a right angle triangle ABC where B=90° We can define following term for angle A Base :  Side adjacent to angle Perpendicular: Side Opposite of angle Hypotenuse: Side opposite to right angle We can … Continue reading trigonometric formulas for Class 10 »

## Vertical line test for functions and relation

A relation is a function if no pair of the relation has the same first elements. On the graph,two points will lie in the same vertical line if and only if the first coordinate of the two points are same. Therefore if a vertical line intesect the Relation graph at two points then it is not a function. This is called the Vertical line test. If all vertical lines intersect a curve at most once then the curve represents a function

## What is Acceleration of free fall

Free fall acceleration A body falling freely is solely acted by Earth Gravitational force. The falling body is accelerated  by the Gravitational force and acceleration due to this gravitational force is called acceleration due to gravity. Acceleration due to gravity values slightly differs at different altitude and surface .For all practical calculation purpose, we take it  approx  9.8 m.s-2 or 10m.s-2 .Direction is always downwards. It … Continue reading What is Acceleration of free fall »
