To graph a trigonometric function on a TI-84, first make sure that all the "modes" match; that is, make sure that you have everything set either to "degrees" or to "radians". I have things set to radians, so I'll show how to graph in that mode. ...
you can probably work it out based on the equation above or simply going through the opposite of the process described in the previous section. First, convert radians to complete revolutions by dividing the figure by 2π, then multiply by 60 to convert...

wasn't really trying to define sine and cosine so much as I was trying to point out that radians are usually introduced via the arclength of a wedge, not the area of a wedge (divided by 2). Also, I didn't have a problem with using that arclength and area are proportional to the ...
If, for example, you wanted to rotate the surface shown in Figure 3 by π/12 radians (15°) about the x-axis, Rₓ becomes (approximately):To produce the new rotated view P’ of the surface, one simply performs the matrix multiplication RₓP as follows:...
% Compute the translation vector to move from a top-left origin to a % centred-origin T = [-half_width half_height]'; % A lambda function for creating a 2D rotation matrix rotmat = @(th) [cos(th) -sin(th); sin(th) cos(th)]; % Convert angle to radians and generate rotation ...
I have a very similar piece of code. It got me very close results when compared to another implementation. I think the problem with yours is that you are using "distance" as linear distance in meters instead of angular distance in radians. ...
figure. It is the enclosing boundary, or the edge. Theradiusof a circle is a straight line segment from the circle's center point to the outer edge. This can be measured using the center point of the circle and any point on the edge of circle as its end points. Thediameterof a ...
If both angles add up to 90 degrees, you did indeed find the complement of the first angle. Tips Finding Supplementary Angles Because the sum of any two supplementary angles is 180 degrees, if you're given the measure of an angle y, then you can find its supplement or supplementar...
