Explanation Calculation: Refer to Equations (2), (3), and (4) in the textbook to prove the given expression. Write the expression in Equation (2) as follows: x = r cos θ and y = r sin θ (1) Write the expression in Equation (3) as follows: d x d θ = − r sin θ + cos θ d r d θ (2) Write the expression in Equation (3) as follows: d y d θ = r cos θ + sin θ d r d θ (3) Write the expression in Equation (4) as follows: tan ψ = x d y d θ − y d x d θ x d x d θ + y d y d θ From Equations (1), (2), and (3), substitute r cos θ for x , r sin θ for y , ( − r sin θ + cos θ d r d θ ) for d x d θ , and ( r cos θ + sin θ d r d θ ) for d y d θ as follows: tan ψ = r cos θ ( r cos θ + sin θ d r d θ ) − r sin θ

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
