  • 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.…

  • 2.2 Finding Trigonometric Functions of Non-Acute Angles

    This lesson is going to cover how to find the trigonometric functions of angles that are more than 90 degrees and less than 0 degrees. Let’s proceed. Finding the Reference Angle

  • 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,…
