Arccos is used to undo or reverse thecosine function. If you know the cosine of an angle, you can use arccos to calculate the measurement of an angle. Since arccos is the inverse of the cosine function, and many angles share the same cosine value, arccos is a periodic function. Each ar...

The three basic trig ratios are Sine = Opposite / Hypotenuse; Cosine = Adjacent / Hypotenuse; and Tangent = Opposite / Adjacent (often remembered with the mnemonic device “SohCahToa”). Solve for the missing angle by using the arcsin, arccos or arctan function of your calculator (usually ...

meters long and goes down at an angle of 36°. Now we can calculate how much vertical and horizontal space this slide will take. We are basically in the same triangle again, but now we know theta is 36° and r = 4. Then to find the horizontal length x we can use the cosine. We...
Sine and Cosine Step 1 Pick one unknown angle in your triangle, formed by the hypotenuse and one of the legs. Step 2 Calculate the sine of this angle by dividing the measurement of the opposite side by the measurement of the hypotenuse. For example using the angle formed by a hypotenuse ...
Understand that to calculate secant you need only find the cosine of an angle and the relationship that exists between them. So you can find the cosine of angles A and B from the diagram by using the definitions given in Step 2. These are cos A= b/c and cos B=a/c. ...
