As noted above we can get the correct angle by adding p p onto this Therefore, the actual angle is, θ = π 4 π = 5 π 4 θ = π 4 π = 5 π 4 So, in polar coordinates the point is ( √ 2, 5 π 4) ( 2, 5 π 4) Note as well that we could have usedGet stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us! 5 With domain= and samples= you specify at which points pgfplots evaluates your function The plot would therefore start at the xaxis only if such a data point would coincidentally be the root of the function The naive solution would be to increase the number of samples to a ridiculous amount and just hope for the best

Plot+x^2+(y-sqrt(lxl))^2=1
Plot+x^2+(y-sqrt(lxl))^2=1-After a little manipulation, we reach x=3\sqrt {2x^2} A reasonable thing to do is to square both sides We reach x^2=1x^2 It is easy to see that this equation has no real solution so there After a little manipulation, we reach x = 3 2x2 As the title says, I want to plot x=1, y=1 and y=1/(2*x), preferably with different colors, and after that, I want to paint the area between the x,y axis and the lines ploted Something like this Thanks in advance r plot Share Improve this question Follow asked Apr 27 '19 at 326
The denominator has only "1st order of smallness" it's just "small" because the #sqrt(x^2y^2)# is around the same size as the x or y So the quotient will be "tiny/small" which goes to 0 "Number sense" If x and y are around 1/100, the top will be about 1/, and #sqrt(x^2y^2)# will be about 1/70, so the quotient is about 7/1000Regarding specific example, I consider this equation TanhSqrtx^2 y^3(y^2 igy 4)Sqrtx^2 y^2 (y^2 igy)Sqrtx^2 y^2 ((y^2 igy 4)/(y^2 igy)) == 0, where {g,0,02}, i is a complex unit, Tanh is a hyperbolic tangent I would like to take, for example, g=01 and for y from 0 to 6 find x=Rexi*ImxThe problem now is to create values for z I've tried to just type the whole equation in, but that gives this result

Plot y^2 = x^2 1 (The expression to the left of the equals sign is not a valid target for an assignment) Follow 15 views (last 30 days) y1 = sqrt(x^2 1); Matlab works with arrays (matrices actually) First, you need to create an array with the x values x = 1 001 5 where 001 is the interval between consecutive values Then you need to calculate to y values y = (x^2 3*x 7) / (sqrt(2*x 5));

Suppose that \frac {x^2} {\sqrt {x^2y^2}}=f (x)g (y) for some functions f and g Then f (1)g (1)=\frac {1} {\sqrt {2}}, It cannot be done Suppose to the contrary that it can be done We will derive a contradiction Suppose that x2y2 = f (x)g(y) for some functions f and g Then f (1)g(1) = 2Therefore, x y = 1 is a part of a parabola we have a parabola if and only if the determinant is 0 ( Details) Here A = 1, B = − 1, C = 1, so the determinant is 1 − 1 − 1 1 = 0, and this is indeed a parabola, truncated because it omits the points where x < 0 or y < 0 Which is a parabolaYou can graph this by using the slope intercepts and the y intercept The slope of this equation is the constant beside the "x", which is Step 1 After drawing the cartesian plane, take your pencil and mark positive 3 on the yaxis Step 2 Since your slope ( the the fourth count ends on, which is on 7, on the y

0 I like all the answers gone before me However, just to add another different (if not longer method) We start by dividing through by x first we find y x y ′ 1 = 1 ( y x) 2 then subbing in v = y x we obtain v ( x v ′ v) 1 = 1 v 2 rearrange we obtain ∫ v 1 v 2 − 1 v 2 d v = − ∫ 1 x d xSelect a few x x values, and plug them into the equation to find the corresponding y y values The x x values should be selected around the vertex Tap for more steps Substitute the x x value 2 2 into f ( x) = √ − x 4 f ( x) = x 4 In this case, the point is ( 2, ) ( 2, ) ratio = sqrt (11/ (kr)^2) With k and r on the x and y axes, and ratio on the z axis I used meshgrid to create a matrix with values for x and y varying from 1 to 10 x,y = meshgrid ( 1110, 1110);
That might not get you all the way (because the square root has more than one solution) but it's a start Two things to note You need ^, not ^ Observe that, #sqrt(1x^2) and sqrt(1y^2)# are Meaningful, iff, #x le 1, and, y le 1(star^1)# This means that, there is no Harm if we let, #x=sintheta This issue is preventing me from making a surface plot, as I am told that Z is a scalar or vector (because the program computed it as that for some reason), rather than a matrix
Stay on top of important topics and build connections by joining Wolfram Community groups relevant to your interestsY=f (x) The y is to be multiplied by 1 This makes the translation to be "reflect about the xaxis" while leaving the xcoordinates alone y=f (2x) The 2 is multiplied rather than added, so it is a scaling instead of a shifting The 2 is grouped with the x, so it is a horizontal scalingLearn more about plot MATLAB I note that your example has the wrong sign on the y^2 term, which is irrelevant, since your example is perfectly valid

To graph the XY plane you set Z = 0 and plot the function as you normally would, so $$z = \sqrt(x^2 y^2 1) == 0 = \sqrt(x^2 y^2 1)$$ $$\text {Therefore} x^2 y^2 = 1$$ is your XY axis graph, which is just a circle of radius 1 centered at the originIf you have already studied the "circle" chapter in 2D geometry,then you can clearly see, mathX^2Y^2=0/math says,the radius of the circle is zero and its centre is at (0,0) So you can say it is a point circle Here is the graph, You can see
