**arctan(1) Step-by-Step Calculator - Symbolab**

Inverse Tangent tan-1 Tan-1 arctan Arctan. The inverse function of tangent. Basic idea: To find tan-1 1, we ask "what angle has tangent equal to 1?" The answer is 45Â°. As a result we say that tan-1 1 = 45Â°. In radians this is tan-1 1 = Ï€/4. More: There are actually many angles that have tangent equal to 1. We are really asking "what is the simplest, most basic angle that has tangent equal... The most common convention is to name inverse trigonometric functions using an arc- prefix, e.g., arcsin(x), arccos(x), arctan(x), etc. This convention is used throughout the article. When measuring in radians, an angle of Î¸ radians will correspond to an arc whose length is rÎ¸, where r is the radius of the circle. Thus, in the

2011-05-16Â Â· then solve for x=cos(pi/3) the answer is 1/2 or 0.5 OR -1/2 or -0.5 since cosine (-ve) or cosine (+ve) will give same result. *this is just a guide on how to deal with trigonometry when you have a calculator at hand....Inverse Cosine cos-1 Cos-1 arccos Arccos. The inverse function of cosine. Basic idea: To find cos-1 (Â½), we ask "what angle has cosine equal to Â½?" The answer is 60Â°. As a result we say cos-1 (Â½) = 60Â°. In radians this is cos-1 (Â½) = Ï€/3. More: There are actually many angles that have cosine equal to Â½. We are really asking "what is the simplest, most basic angle that has cosine equal

An equation says that two things are equal. It will have an equals sign "=" like this: In other words, we want to move everything except "x" (or whatever name the variable has) over to the right hand side. Example: Solve 3xâˆ’6 = 9. Start with: 3xâˆ’6 = 9. Add 6 to both sides: 3x = 9+6. Divide by 3: x = (9+6)/3. Now we have x = something, and a short. How to sell secondhand h&m

### 2010-12-04Â Â· Since -1 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 1 to both sides. tan(x)=1 Take the inverse tangent of both sides of the equation to extract x from inside the tangent. x=arctan(1) Take the inverse tangent of 1 to get (`)/(4). x=(`)/(4) Simplify the expression to find the second solution.
