An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable.
e.g Legendre & Hermite polynomial
angle of contact.
It is defined as the angle between the tangent to the liquid surface at the point of contact and solid surface inside the liquid is called as angle of contact The value of angle of contact depends upon (i) Nature of solid and liquid in contact (ii) Cleanliness of the surface in contact (iii) Medium above the free surface of liquid
