This Excel tutorial explains how to use the Excel ATN function with syntax and examples.Description The Microsoft Excel ATN function returns the arctangent of a number (expressed in radians). The ATN function is a built-in function in Excel that is categorized as a Math/Trig Function. It ...
The cumulative sum of the rotation angles gives the angle of the original vector, corresponding to the arctangent (y/x). The CORDIC algorithm can also be used for calculating hyperbolic functions (sinh, cosh, atanh) by replacing the circular rotations by hyperb...

How to Use a Scientific Calculator The obvious way to learn to use the calculator is to read the manual. If you got a calculator that didn't come with a manual, you can usually search for the model online and download a copy. Otherwise, you need to do a bit of experimentation or you...
Related to this Question Find the equation of the tangent line to the graph of y = (2x + 3)/(3x - 2) at the point (1,5) using the quotient rule. if Y=5X^2+3 then the tangent at X=0, Y=3 is Find the equation of the tangent line at the point (0,0) on the curve give...
2π is equal to a complete revolution around the unit circle, or 360°. What are the trig functions and how do they relate to the unit circle? The primary trig functions are sine, cosine and tangent. On the unit circle, sine corresponds to the y-value, and cosine to the x-...
