i keep getting a negative number when i try to do tan40 The tangent of 40 radians is a negative number.

how do i graph a circle in parametric mode? The simplest way is X1=cos(T) Y1=sin(T) Set angle unit to radians, Set the Zoom window to SQR (square), otherwise your circle will look like an ellipse.

...degrees assumed): [sin] 45 [EXE] Cosine and tangent are analogous. Argument format can be degrees, radians or grad. You can set up the angle argument unit by keying in: [SHIFT] [SETUP] [v] [v] [v]

How to garph cos^-1 x Select the GRAPH utility.In the screen that opens, make sure the graph type is set to function Y=.If not set to function, press F3:type and select itHighlight Function Y1=, and ...

If I have an answer in radians, how do I get the calculator to how me the answer in fraction form? By definition, a fraction is a number that is represented by the ratio of two integers (whole numbers

...chain rule. d/dx(f(g(x))=d/dg(f(g))*d/dx(g(x)) d/dx(sin(cos(x))=-sin(x)*cos(cos(x)) if x is in radians. If arguments are in degrees, you have a factor (Pi/180)^2 The bad news is that this ...

how do you find sine cosine and tangent on a fx-9750g2 calculator? First you must setup the correct angle unit (as required by the problem you are solving). Open the [Run] application screen. Press ...

...;: just an example The 1st element of List 1 is the radius, and the second element is the angle (in radians). Convert it to degrees if you wish. I won't do it. Now you must extract each element and ...

...As to the value of sin 45 you quote, you should be aware that it is valid for an angle unit in radians. It is an approximation because the radian unit is based on the value of pi, which, as I ...
