• ### Concept of Anti Derivatives or Integration

The inverse process of derivatives called anti–derivatives or integration. “A function being given and it is required to find a Second function whose derivative with respect to x, is, that is, Thus if Then The function , then, is called the anti-derivate or indefinite integral of . Symbol of Integration: The function is called integrand […]

• ### Application of Differential Equations in Physics

Differential equations are commonly physical problems. In the following example we shall discuss a very simple application of ordinary differential equation in physics. Example: A ball is thrown vertically upward with a velocity of 50m/sec. Neglecting air resistance, find (i) Velocity of ball at any time (ii) Distance travelled in any time (iii) Maximum height […]

• ### Application of Differential Equations in Biology

Differential equations are frequently used in solving the mathematical and physical problems. In the following example we shall discuss application of simple differential equation in biological sciences. Example: In a culture bacteria increases at the rate proportional to the number of bacteria present. If bacteria are 400 initially and are doubled in 3 hours, find […]
