So, to be able to solve them, you need to understand the various trigonometry formulas. Also, a single trigonometric problem may require more than one formula. So, learn how you can apply multiple formulas to the same trigonometric problem. Trigonometry formulas are used for a variety of ...
For each, substitute its respective y-value found in Step 3 into the equation and solve for x. Let's start by finding the maximum point. {eq}2 = 2 \cdot cos(x + 1) {/eq} Divide both sides by 2. {eq}1 = cos(x + 1) {/eq} Apply the inverse cosine function to ...
Let's say I need to solve the equation cosx = 1/3 using a calculator. Now I know that I could take the inverse cosine of both sides of this function and end up with x equals the inverse cosine of 1/3. This inverse cosine is also known as the arccosine, and on the CLEP calc...
