However, we can make two equations using x and y. Equation 1 tan 40º = x y Equation 2 tan 30º = x y+100 Replace tan 40º with its ratio and solve for x in Equation 1..8391 = x y or x = .8391y Replace tan 30º with its ratio in in Equation 2. .5774 = x y+100 Substitute value of x from Equation 1 in Equation 2. .5774 = .8391 100 y y+ Solve for y.

Verify the fundamental trigonometric identities. Identities enable us to simplify complicated expressions. They are the basic tools of trigonometry used in solving trigonometric equations, just as factoring, finding common denominators, and using special formulas are the basic tools of solving algebraic equations.

Example 3: Express y = (3/4)x – 7 in general form. Example 4: Express y = (3/4)x – 7 in intercept form. Example 5: Find the equation of the line parallel to the line x = 8 and passing through the point (5, –17). Example 6: Find the equation of the line (in point-slope form) passing through (–1, 6) and perpendicular to
The article focuses on using an algorithm for solving a system of linear equations. We will deal with the matrix of coefficients. Gaussian Elimination does not work on singular matrices (they lead to division by zero).
