Then, you can use inverse trigonometric functions or a calculator to find the value of x. What are the different methods for solving trigonometric equations?There are several methods for solving trigonometric equations, including factoring, using trigonometric identities, and using the quadratic formula...
Subtract from both sides of the equation: . Divide both sides by : EXPERT TIP Joseph Meyer Math Teacher To solve an equation for a variable like "x," you need to manipulate the equation to isolate x. Use techniques like the distributive property, combining like terms, factoring, adding or...
While quadratic equations have two solutions, cubics have three. You already have two of these — they're the answers you found for the "quadratic" portion of the problem in parentheses. In cases where your equation is eligible for this "factoring" method of solving, your third answer will ...
Use techniques like the distributive property, combining like terms, factoring, adding or subtracting the same number, and multiplying or dividing by the same non-zero number to isolate "x" and find the answer. 7 Take the square root of both sides of the equation. You should now be left ...
