WebMar 27, 2015 · This seems to be written wrong, there is no real way to solve cos x = 2. If the task were tan ( arccos ( − 2 / 2)) then one knows from the elementary trig values that cos x = − 2 / 2 has the solutions x = ± 135 °, so that arccos ( − 2 / 2) = 3 π 4 and the tangent of that is − 1.

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. … WebAug 1, 2024 · This works better with decimals, so we'll switch from 1 3 to 0.¯ 3. Step 1: 1000 × 0.¯ 3 = 333.¯ 3, which we'll round to 333. Step 2: 1000 − 333 = 667. Subtracting from 1000 is easy.

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.
