Why is Arctan 0 Not Pi? Arc tan 0 = 0 but not pi. Though both values of tan 0 and tan π are equal to 0, we say that arctan 0 = 0. This is because the range of the inverse tan function is (-π/2, π/2). What is Arctan 0 in Degrees?
Using the Cosine Ratio to Find the Angle Check the mode of the calculator. On scientific calculators it is displayed on the screen. For graphing calculators, press "Mode." If you are using degrees (generally, if you are in geometry), the calculator should be set to degrees or "deg." If...
To Calculate Arcsine, What Buttons Do You Press on a Scientific Calculator? When using scientific calculators for tests, memorize the locations of keys such as the arcsin beforehand. Doing so will allow you to confidently work equations and be more efficient on time-sensitive tests. Definition Ac...
How do you do sin-1 on a calculator? In some calculators, there is no "arcsin," or "sin-1" button. Instead, youhave to push a "shift" or "function" key, then push the normal "sin" button. Is COT the same as tan 1?
How to find the radius of a circle What is the derivative of y = 3/x^3? Without using a calculator find the exact values of arctan sqrt 3, arccos (sqrt 3)/2, and sin^-1 (sqrt 2)/ 2. Evaluate these exact values, using the angle identities: 1) \sin 165^{\circ} 2) \cos ...

Grams to Troy Ounces Enter the number of grams of gold or silver you have into your calculator. For this example, consider 100 g of gold. Press the division sign. Enter "31.1" -- the number of grams in a troy ounce. Press the total sign ("=" on most calculators). The result is ...
How to find the number of sides of a polygon using the given angle? How do you add coefficients with exponents? Convert 7.6029x10^-5 to standard number form using a calculator Without using a calculator find the exact values of arctan sqrt 3, arccos (sqrt 3)/2, and sin^-1 (sqrt 2...
I am trying to make a programme to convert cartesian coordinates to polar coordinates. My calculator returns arctan(1) as pi/4. MATLAB on the other hand returns atan(1) as 0.7854. How can I get MATLAB to return numbers like this as expressions of pi?
In the math module, I could only find cos/sin/tan/acos/asin/atan. These take the argument, respectively return the answer, in radians. How can I use degrees instead? Here's my code: import math x = math.cos(1) y = x * 180 / math.pi print(y) 30.9570417874 My calculator, on ...
