Product Rule of Differentiation 150 150 SchoolTutoring Academy

Product Rule of Differentiation

The product rule of differentiation is a rule for differentiating problems where one function is multiplied by another function. According to this rule, first function times the derivative of second function is added to second function times the derivative of first function. If h and g are two functions of x, then the derivative of…

Converting between Radians and Degrees 150 150 SchoolTutoring Academy

Converting between Radians and Degrees

Radian and Degree are the most commonly used units to measure angels. Angle in degrees is denoted by symbol °  e.g. 50°. The radian is represented by ‘rad’ or by superscript c e.g. 45 rad or 45c. To convert between radian and degree we make use of the fact that 360° is same as 2π…

Six Trigonometric Ratios 150 150 SchoolTutoring Academy

Six Trigonometric Ratios

In greek ‘Trig’ means triangle and ‘metic’ is for measurement. The Trigonometric rations are used to express relationship between angles and sides of a right triangle ( a triangle with one 90° angle). The non-right angle is usually designated by a greek letter θ (theta). The sides of the triangle are labeled according to the…

The Coordinate Plane: Understanding Quadrants, Coordinates, and the Origin

The coordinate plane is a two-dimensional surface where we can plot points, lines, geometric shapes and curves. The coordinate plane is also called as Cartesian plane. It was invented by the French mathematician Rene Descartes in the 17th century. The coordinate plane has two scales (number lines) perpendicular (at right angle) to each other. The…
