Biogas plants use these dried plants as raw materials. Capturing this energy storehouse from woods, crops, algae, animal and human wastes, o..

Finding the solution by the method of substitution. Finding the solution by the method of substitution. (i) Coefficients of one of the variables (say x) in the two equations are made equal, by multiplying them with suitable factors. (ii) By addition or subtraction, this variable (x) ..

A homogeneous differential equation is solved by using y = vx and transforming the given differential equation to a variables separable form in x and v. To solve homogeneous differential equation we use the substitution. y = vx The equation reduces to variables ..

Mirror Formula - In a spherical mirror, the distance of the object from its pole is called the object distance (u). the distance of the image from the pole of the mirror is called the image distance (v). You already know that the distance of the principal focus from the pole is called the focal len..
