If one expression contains several variables the overall degree of the expression is the sum of the powers. For example, the expression p2q3r4 has a degree of 9 overall (it is a second-degree expression in p). The degree of a polynomial is the degree of the variable with the highest power, e.g. ax5 + bx4 + c has a degree of 5. 4 The highest power to which the derivative of the highest order is raised in a differential equation. For example, (d2y/dx2)3 + dy/dx = c is a differential equation of the third degree (but second order). |
