2.3 How to Find Trig Function Values Using a Calculator
So far, we haven’t had much use for a calculator with our math operations. Going forward, we might want to check what exactly the value of a certain function is, or find it’s inverse. Using a calculator to find trig function values is important to be able to check our work and for various applications.…

2.1 Trigonometric Functions of Acute Angles
One way to remember the trigonometric functions is through the acronym SOH CAH TOA. In the illustration above, we are shown what each respective side of the triangle is labeled, and now we can use this to apply to SOH CAH TOA. SOH = sine, opposite, hypotenuse CAH = cosine, adjacent, hypotenuse TOA = tangent,…
