WebFirst, we are taking the arctangent of 2. That is, we are finding some angle 𝜃 such that tan 𝜃 = 2. Then, after finding that angle, we are taking the sine of that angle! In other words, if we have an angle 𝜃 such that tan 𝜃 = 2, we must find sin 𝜃. … WebCosine calculator Arccos definition. The arccosine function is the inverse function of cos(x). arccos(x) = cos-1 (x) For example, If the cosine of 60° is 0.5: cos(60°) = 0.5. Then the arccos of 0.5 is 60°: arccos(0.5) = cos-1 (0.5) = 60° Arccos table WebRAD mode stands for "radian". This means that your calculator interprets and outputs angles in the unit of radians. If you are not sure what radians are, I suggest you watch the KA videos on them. Switching between DEG mode and RAD mode on a calculator is similar to switching between "miles per hour" and "kilometers per hour" on a speedometer. earth\u0027s lower mantle
