WebFeb 1, 2024 · Firstly, we choose the cosine, i.e., cos (x) \cos(x) cos (x), from the list. Once we have that, we move to the variable field below, which contains the angle. We input 45 ° 45\degree 45° from our problem, and the moment we do that, the cofunction calculator will spit out the answer underneath: the cofunction along with the value. WebCosine The Cosine of angle θ is: cos ( θ) = Adjacent / Hypotenuse And Inverse Cosine is : cos -1 (Adjacent / Hypotenuse) = θ Example: Find the size of angle a° cos a° = Adjacent / Hypotenuse cos a° = 6,750/8,100 = 0.8333... a° = cos-1 (0.8333...) = 33.6° (to 1 decimal place) Tangent The Tangent of angle θ is: tan ( θ) = Opposite / Adjacent WebMethod 1: Decimal. Enter a decimal between -1 and 1 inclusive. Remember that you cannot have a number greater than 1 or less than -1. Method 2: Adjacent / Hypotenuse. Entering … edge measurement
