Methods of Differentiation Here we will learn methods of Differentiation, We had already studied the two meanings of derivative(differentiation) of a function which is the geometrical and physical meanings. Since we know what does the differentiation of a function means…
Differentiability The concept of the differentiability (derivability) of a function tells us about whether a given function will be differentiable or not. If the function is differentiable then we will use Methods of differentiation to differentiate a function. Actually, this…
Continuity of a function we had studied about limit of a function at a point now we will study about the continuity of a function, what does it means for a function to be continuous at a point ? how…
Know Functions, Types of Functions, What is Composite Function ? Periodic Functions ? Properties of functions. You should learn set theory and relations before learning about functions. Functions A function defined from set A to set B is a special…
THREE DIMENSIONAL GEOMETRY ( PART – 2), THE PLANES THE PLANES Plane is the surface such that if any two points are taken on it, then the line joining the two points lies on it. General equation of plane is…
THREE DIMENSIONAL GEOMETRY ORIGIN In the following diagram X’OX , Y’OY and Z’OZ are three mutually perpendicular lines , which intersect at point O. Then the point O is called origin. COORDINATE AXES In the above diagram X’OX is called…
INVERSE TRIGONOMETRY FUNCTION INVERSE FUNCTION If f:X⟶ Y is a function which is both one – one and onto, then it’s inverse function f^-1:Y⟶X is defined as: y = f(x) ⟺ f^-1(y)=x Such that , ∀x∈X , ∀y∈Y INVERSE TRIGONOMETRY…
PROPERTIES AND SOLUTIONS OF TRIANGLE Here, there are some key concepts regarding the properties and solutions of triangles. these are very important for the students who preparing for IIT-JEE and other equivalent exams. POINTS TO BE REMEMBERED LAWS OF SINE…
